I go to Purdue University and am taking a math course online. Every week, my professor puts your videos as required media for us to use along with our textbook. There are no lectures provided by the university or professor. I wish I could have given YOU the thousands of dollars I'm paying for my course instead.
Same here. I hate online math courses cause the teachers don’t do their jobs and leave it to the books, YT videos, and online learning. I feel like I’m not learning anything, it’s so frustrating! It’s such a rip off!
This UA-camr is a legend ✊
What kind school is that…
Thank you soo much, I was struggling and my teacher isn't very good at explaining this
Or you weren’t listening 😝
Wolf Storm Wizard no, my teacher really just couldn’t explain it in a way I could understand.
I wasnt listening plus I couldnt be there for some of the lessons
Same
Dead ass it’s like teachers became teachers just to make kids life’s worst
I'm homeschooling and your videos have made learning Algebra fun!
i may or may not be watching this during the test
Hmmmmmm. Well at least you’re learning it instead of straight up searching it up like me. 😅😅
WHY can this wonderful man make it so clear? My textbook has the coherency of sawdust.
They tend to skip a bunch of stuff and not explain how they got the answer. Math textbooks aren't the best =_=
Pretty rare a professor of mathematics can explain or write coherently
@sjisjsissk But people do pay a lot of money to get knowledge,why don't they explain it clearly for the learners to understand?so sad.
LMAOO😂😂
You explain better than my teacher, without you, I might've failed my first math quiz tomorrow for the new semester
hi yeah this is a great resource
so hows life dawg
OMGGG TYSM SIR my teacher didn't even teach us this method! I am now feeling very confident on my exam tomorrow you had just wiped my tears of frustration out of my face. Bless you💚
Bruh u are a genius and a life saver you explain better then my teacher! God bless you!
I'm dying inside I still don't understand it
* shocking *
I never understand anything in math
Booga04 Minecraft lollll sams

He's multiplying the radical values with each other, and simplifying them. When working with radicals, you have to break down the value in the radical and see if you can find the square root of one of those values. That root can be placed outside of the radical sign and multiplied with it. Similarly, to put a multiplied number into a square root radical, you have to square it and multiply it with the existing number inside the radical.
@@sachinraghavan4556 It still doesn't make sense.
I'm really thinking of suicide I really don't have time for this shit even I'm smart never understands math 😐
Thank you so much for making this video, I was literally stuck on a problem for days and could not understand but now I do! You rock thank you!
I didn’t get the last one but other ones help a lot thank you very much👌👌💕
what dont you get? its just factoring out x^2+6x+9. you need 2 of something to take it out of the radical right? just like if 9 was in a radical or (3)(3) it would be 3. you have the same expression twice- (x+3)(x+3) in a radical = x+3
Your videos are just amazing. At home, I've been watching your channe; since, and you've helped me reach another level in math. Thank You SO much
MR. Organic Chemistry Tutor ,thank you for another excellent video/lecture on Multiplying Radical Expressions With Variables and Exponents in Classical Algebra. These are powerful tools in Mathematics, Physics, and Engineering.
I've been struggling for the longest on the part with variables, but this explanation was so easy to follow and added so much clarity for me. Thanks!
Best guy on math subject
My head is literally exploding. You are so talented at math oh my gosh and the way you described it all? EN POINTE. Jesus bless you. You are literally a light worker on earth for all of us.
Fantastic !! Thank you for all you do.
This is gonna be my new lesson on my Math and I really thank you about it🙏😁
bro thank you so much you really helped me I wish you success
You helped me get a B on my midterm in college, thank you ! 😊
This helped a lot Tysm I have my math final exam in 3 days
thank you this made it so easy to make
If only I could like your videos more than once I would
you are so much better at this than my teacher
bro youre so wild for this i love you
you are such a good teacher...........we thank you🥰🥰🥰🥰
Needed a brush up bc its the Night before milestones thx bro
These videos are amazing thank you so much
Thanks you are so eloquent
Awesome video!
Thank you so much. God bless you
Best math teacher I've ever had
Thank god that youre vid is free to dl
THANKYOU SO MUCH I GET IT
Math is so hard ༼;´༎ຶ ༎ຶ༽
bruh we literally have a test abt this in like 20 mins
how did you do ka?
Thanks!
Youre my teacher now
This guys teaches better than my Math teacher.
Your voice is great
This method for breaking up radicals is meta as hell
thank you i love you
Much love
Bro is the reason I'm not failing math💀😂😭

I but if it is x to the power of 3 squared what is the square root of that?
This is really HARD I CAN'T 😌😌😌
Ayeee galing mo tlaga mam
Please answer this. Im so confuse. The questions on my assignments seems to be different. Our topic is multipliying radicals but what our teacher taught is really different. When i try to do your method, the answer given by our teacher from his example is wrong. ^3√54x^5 multiply by ^3√48x^4.. I keep on trying to answer this on my own from the way you teach. But the answer was still not the same from our teacher. I dont get it. Please help me.
That’s just sad, no one has replied helping you in 2 years
Did you figure it out?
its been three years and they still didnt figure it out.... im so sorry...
its been three years and they still didnt figure it out.... im so sorry...
@@77lowend 4 years still no helped him. prolly graduated by now
Genious in math..how to be you?
Thank you I understand it now am in 7grade but learning 8grade math because I am good at it
Hope all.
What if the index is different
So if you combine two like radicals it will be the same number now I get it.
I think what he's trying to say is that when multiplying roots that you multiply the coefficients.
Basically
you going to fasssst
i have a question in 7:37 when factor 12 using 6*2 would still get me the right answer?
no, u will have to get the cube root of 12. cube root is multiplying the same number three times, in number 12 cube root is 4 (4×3) and then simplify 4 so it becomes √2 and √2 and then √3
On 8:07 why can’t u just multiply 6x3? I’m really confused on this topic..
Your the reason I’m passing
Me watching this an hour before my test 😢
I am looking for a problem that deals with absolute value expression
i still don’t get it
5:11 what if it could be 9 and 8?
I can’t even understand my teacher lmao
what if the index number is different
why is the square root of 6 times the square root of 15 = 90 but the square root of 3 times the square root of 3 = 3? 1:08
hi! this is because √3 x √3 = √9 and finding the square root of 9 equals 3. he simplified it.
how come in the beginning you said 3•3 stayed as a 3( 1:04) , but then in the next example you said that the 5•5 would be 25 ( 2:12 ) i'm SO confused
You could do either way for either of them, they get the same answer multiplying the same two sqaure roots will be the same as when you square root them after multiplying them.
wouldnt when u multiply, lets say root 5 times root 5 = plus or minus 5? why does it equal 5??
Most times teachers only want the positive answer, yes sqrt of 25 is technically-5&5 but most teachers say to only put the positive unless it is asking for both. If the question is Xsquared = 25, what is X? Then you want to put both -5 & 5. That’s what I’m assuming and it works better here to put positive
Im dead tmrw
so basically you are breaking whole numbers into their prime factors?
Basically. You’re just factoring and breaking into primes.
still i dont understand :((
3:55 why it wasnt 3 cube root 2? Anyone??
Its cube root not square root
Can anyone explain how he got x4 and y3 on 7:18
It's a cubed root, so he is looking for groups of 3. x^13 can have 4 groups of 3 taken out of it with 1 x remaining. y^10 can have 3 groups of it taken out of it with q remaining. A good tactic to use would be to just subtract. For example: you want to get how many groups of 3 in x^13 (like in the video above) so you subtract 3, you get 10, subtract 3 again, you get 7, subtract again, you get 4, subtract again, you get 1. You can't get 3 from 1, so the amount of times you subtracted is the exponent you put on the variable once you take it out of the radical (square root)
Daviel Cruz thankyouuuu😭
5:38 , 8 doesnt have square root but cube root so why √x^8 turns to x^4👍😢😩
Think of its like this sqrt(x^4)^2, since you're taking the square root, the two cancels out. You're just breaking down the exponent to a point where it can be rooted.
fvck yea man im pro mathematician now thanks to you brother ffrom another mother
i love you
Isn't 18 already a perfect 4th root?
TheAmazing Bros no it’s not
can you help me
❤❤❤
two times tree :)
Two trees😁
@@disturkgalhere5044 two times tree is 6 trees
Bro stop looking at the comments and listen
god okay man
hoe about square root • cube root?
how*
Dude, I love how you show two ways of doing this but for some reason, u choose to multiple the S.Q of 8 with the S.Q of 6 without showing us how to simplify before multiplying. 1:40 so annoying. My answer was 2 root 12 not 4 root 3.

ITS STILL HARDDD
3xcelent 😘😘
I still have no clue
It had to be you...
Why is every math video involve whispering as quietly as possible
ANO BA YAN, ANG SAKET SA UTAK

What the Hell well I F
Why am I in the smart kid's section of UA-cam?
Mr. UnKnOwN youre not. we're all here cause we the dumb kids lmao
😢√2 • ³√2 • 6√2
I just hate maths......😤😤😤
Good vid I understood most of it, I do have one complaint though, WHY ARE YOU SO QUIET! At first I thought my laptop had a problem but then I realized it was YOU! Sry but because of that I could NOT and I mean could NOT have a harder time to learn then this! Stop whispering and start talking properly
he talks fine, maybe its your laptop
This still didn’t help I’m complete lost
just analyze it my dude and you'll get there. take notes too and follow whatever the hell he's saying.
Jesus, math is so stupid its actually insane. Just seems so impractical and useless. Otherwise, great vid
I mean it's actually used in everything from counting money to building structures so I get your frustration but it's actually more useful then you may think
