I am in Calculus and had to go back to these exponent rules because I did not understand fractional exponents as well as I do now. Thank You so much for refreshing my knowledge on fractional exponent because I need to know these well to find Critical numbers. My professor loves to add fractional exponents on the quizzes and exams; therefore, if I am not a pro at this concept, even though I know the Calculus, I am defiantly in deep trouble. My answer will be wrong because I have to always simplify to the lowest extent. Thank You for giving me some free education, you do not know how much you have helped me.
My teacher spent 90 minutes trying to teach this and still failed at it. and now i perfectly get it from your video. thank you so much
Thank you for helping this teacher prepare for his math certification exam tomorrow! You are an excellent teacher...may God bless you!
you're definetly the best guy making math videos for youtube
you have no clue and yet... you post the longest most rambling stuff. i love the internet
make sure you have mastered basic arithmetic - most people still can not add fractions with numbers, so when you throw variables in, it is : game over man, game over
I had to come back to this lesson Eventhough iam a calc2 student . I pinpointed my weaknesses in math and now im using your videos to cover up that. Thank you sir
You have taught me in 10 minutes what I couldn't grasp in 3 years. THANKYOU
Taught me better than my own teacher! YOU DA BEST!
You are a life saver. Its been years since I have had to do this type of math and your video was a great refresher!
Yo, this was super helpful, i ended up missing a week of class and this really helped prep me for the test.
@TheMaaneetLuver no problem, happy to help!
so helpful! my teacher didn’t teach us anything like this all year and then it showed up on the final exam review. you really pulled through!
Thank you! You are my only professor in my self-conducted college application review, and yet you make it easy for me. Thanks a lot!
thanks alot man. This really helped me out. My math teacher never explained this to us even though we got questions like these on our homework.
Thanks! you are a life saver. I am not a math gifted person, and my teacher doesn't help much, so I appreciate your help :)
I am less stressed out about this upcoming school year because of this thank you Patrick!!! :D
I'm always relieved when I don't know something and see your video. Thanks :)
@addiktion13 ok, sounds good! : ) also, did not mean to 'call you out', just wanted to clarify things for you and others! it is certainly a common little mistake though, one that i am sure i have also made!!
OMG THANK YOU!
took me long enough time to help me with my math exam review :)
Your my hero to the max for this
This video really helped ! My math teacher didn't go into details on how to do this with negatives, so thanks !
@spuddapotato2494 you are very welcome : )
MUCH BETTER THAN MY HIGH SCHOOL MATH TEACHER!!! THANK YOU
This was the most helpful video for me that is about fractional exponents! Thank you so much!
excellent! glad it helped
@deco101 u r very welcome
@fafase Not exactly. What people don't get is that -x^2 isn't the same as (-x)^2. Since exponents are done before multiplication, and that the negative sign is basically multiplying by negative one, you have to do the x^2 first before giving the x a negative value, in the first one. In the second one, the multiplication by negative one is done before the exponents due to the parenthesis. That's why
-x^2 is always negative, and that (-x)^2 is always positive.
haha. great! i missed two classes this week and we have a test next class. THANKS FOR THE HELP! you explained it so well. I've never done this before and i'll be fine for the test just from watching your video!
i am not sure how to help you on the programming end of things... i took a C class, but that was about 10 years ago...
Why is 8^2/3 the same as [8 1/3]^2? What's the reason/logic/rule behind getting that result?
Keni Angervo When an exponent is taken to the power of something you can multiply them. Ex : (2'3)'2
That's 2'3 • 2'3. Instead of writing it out like that though, we can just take the '3 and '2 times each other and get '6. The answer is 2'6 or 64
Keni Angervo Now, because you can multiply an exponent multiplied by an exponent, you can see how (2'1/3)'2 is equal to 2'2/3 because 1/3 • 2 is 2/3
Today I have seen all the exponents , and I have understood everything so thank you teacher :)
Thank you so much I'm finally able to understand this!!
(like)(like)(like) is like to the third power. Very clearly presented.
Obey the Laws of Exponents!
You are the best teacher nooooooooo doubt !!!!!!!!!!!!!!!
omigosh that last problem was fun! :D
Thank you so much! I missed this lesson and now i understand. Can you explain how to write a radical expression as a power with positive exponents please!
no problem!
@PenguinSplash no problem
i'm a senior in college and this saved my ****ing life.
how do you factor quadratic equations with negative exponents or fractional exponents? A video on that would be much appreciated.
i have a video on that somewhere
In Algebra 1( 9th grade). this helped some. Thanks for posting video.
Was looking for: Evaluate integers raised to rational exponents.
Thank you soo much it really helped and i have a big math test today!
Man all I had to do was break down the expression, thanks for posting this vid.
Thank you so much, you are a better teacher than my own.
glad i could help!
Amazing! Thanks so much!!! I registered for a class that's a little much for me and you're helping me catch up! Thanks!
@djjoelroche less stress is always good : ) feel free to visit during the school year... patrickjmt is always here, boring someone : )
This is the value of the internet in modern education.
@xGUNxBUNNYx happy to do so - a useful skill in math is taking a big problem and trying to turn it into many smaller problems!
wow really didnt realize how fast you forget things ... thanks for the reminder man
actually, i would use a taylor series representation to get the desired accuracy. that would work
glad i could help :)
The problem with (-9^3/4)^2 ,a later step, you did (9^3/4)^2/1. The last few steps of the last problem (5/6)^2 to get 5^2/6^2 why are they not the same? Why the last problem isn't (5/6)^2/1 to get 5^2/6^1?
you are are best maaan!!!!
no one can do this better than u
Yes, it is. I can't stand XL. I always end up figuring it out on my own, or watching this guy who knows what he's doing.
thank you so much omfg I can't even, I missed school a lot bc I was sick and teacher didn't even try to explain me what I had missed so I didn't really understand any of these since they look kinda scary when you first look at them and I tried to understand them for myself but failed miserably, anyway, bless you, ur great!
thank you so much I finally understand. Your method works. God bless you.
@jeleemay97 glad i was able to help you : )
thank you so much for uploading this
Thanks for the review, it was very helpful.
QUESTION!: If you have a problem that says: x raised to 3/4 PLUS x raised to 5/8, how would you do such a problem?
i was always told that whenever you take a number in the numerator that is attached to a neg. exponent and put it in the denominator, you take away the negetive from the exponent and then flip the powered fraction. for instence 8 to the neg 1/3 squared should be 1 over 8 cubed, squared. i dont get it. i thought you also fliped the fraction when you take its attachment in the numerator and place it down in the denominator. a little help please!
@patrickJMT I would have said the same until I checked on my calculator and yes, Juan got over excited. Yet, I don't totally get it. Ex: -3^2=9 but -(3)^2=-9 isn't it?

"Well, now we have addition"
Me: Boo you addition! :P
But thanks a LOT! Your video made so much sense! I was like a mathematical headless chicken running around before I saw your video. Helped me a lot!
You just made my SAT Math score go a little higher :D
Thank you so much sir i've completed this series
I just want to say how much you saved my ass... Finals are inbound for me, I learned how to do fractional exponents now. (Shame on me for falling asleep in my 1st period Int. Alg classes)
unless you are in second grade, no one uses an 'x' for multiplication
@GLORYdubstep i also do not like it, but it was all i had at that time
Super helpful!!! Thank you
Your math help is usefull. I still feel like knoosing myself tho after looking at my page after an hour.
Thank you! That was incredibly helpful!! =)
I need to calculate e raised to various powers of pi, where e = 2.718... and pi = 3.141...
for example, e^pi, e^pi^2, e^pi^3 ...
How can I do this? I have tried by writing a Java program, but there is no power function in Java for fractional exponents.
patrick, this is by far the best explanation on youtube. other methods arent nearly as clear or simple. thank you. it was my pleasure to watch you do this!
thanks bro this was very helpful
damn, nice straight line
Nice tutorial. Is it possible you could evaluate (-1)^(2/3). According to the method you shown, the answer should be 1.(Hint) 1 is not the answer!.
do u have a tut. that show fractional exponents power to fractional exponent?
ex. (2^2/3)2/3 or sumthing like that? or is that even possible?
I dominated at this in middle school, I'm now 22 and can't remember ANYTHING. Thanks for the vid man.
What if the number is replaced by an 'x'? How would you find the answer for 'x'?
Awesome video!! Thanks!
you just saved my midterm grade
Super helpful. Thank you.
Your an absolute legend no detention for mes
Your drawings are awesome
@misspoplover thanks : )
ohmygod. thank you so much! yer my lifesaver!!
mann you are smart can u give m ejust some general advise to help me with my math because i suck and i need to get better
You never fail to please me :)
i ran out of paper when i made this ( the non-lined type at least!)
Wait, on this problem 27^5/6*27^-1/3 why did you discard the other 27? Ins't it also part of the problem?
X^A*X^B = X^A+B
27^5/6*27^-1/6 = 27^5/6+(-1/6)
27^(5/6-1/6) = 27^4/6 = 27^2/3 = 9
Thank you, very good job
Lol, u should be my teacher....soo much better than my algebra teacher...
you are my hero
thanks it helps me alot :)
Thank You!
Thank you🙇
What if unknown number raised to 3/4 = 8? How to solve this
THANK YOU
dude thanks!
thanks for making this video XD
now i actually understand fractional indices..lolz
