I had logarithms in maths in high school (45 years ago) I am 58 and half years old, now I am trying to "revive" this as I must help my daughter that is starting high school as she has a learning disability (global delay and she's a slow learner), she learns but she takes longer than other kids to get the things especially maths, now I must retrieve all I had in my prehistoric times when I was her age and having all this of logarithms, algebra, trigonometric calculations and the rest of this madness called maths and trying to help her with this that is a nightmare but I am getting some maths books and digging into my long past learning again.
I can't believe I just found your channel, you're so much better than any of the other A Level maths videos becuase they're so long and outdated. Thank you so much!
I was having a breakdown about my math test tomorrow because as much as my teacher went over and explained the topics, I didnt understand but this really helped me out a lot!! Thank you so much!!
This was freakkingggg amazing.. I usually dont comment on youtube videos but urs was worth it.. Love it so much, love how you taught from the basics.. Definitely acing my exams.. thanks a ton Sarah 😍❤
Thank you so much! this was really nice as it was more of a "do it yourself" to test our understanding. It was short and understandable and the questions were good, thank you a lot!
Hi, Ive been struggling with Logs with almost a year now (Couldnt get my head around the notation) but this video was helpful. However yo missed out the natural logarithms sections and e.
5:36 Isn't 16 to the power of half equals to 8? I have done it on calculator and i got 8, and i'm getting confused how you got 4 8:42 how 81 to the power of three quarter equals to 27, on calculator i am getting 132860.25. And how 64 power half can equal to 8, isnt it 32? if anyone could help me i'd be really grateful
first one- 16 to the power of a half is 4, as you put 16 to the root of the denominator (2) and then square it by the numerator (1). same for the others: 81 to the power of three quarters, the denominator is 4, so the cubed root of 81 is 3. then square that three by the denominator (3) to get 27. 64 to the power of a half: square root of 64 is equal to 8, to the power of 1 is still 8. hope this helps
Even if she did square root the 9. She would have to do it to the other side of the equation to. So square root of 4 = 2 and square root of x^2 = x so she'd have 2x = 3 and then x = 3/2
BIDMAS only really applies when you are working out an answer and you only have one side of the equation, say: (x+6)^2 - 8 = ? however if you have both sides of the equation already, you can do whatever you want *provided you always do the same to the other side*
i was stressing out about my test on monday but this saved my life. i really don’t know how to thank you! have an amazing day.

You're so amazing for this
tell your daughter to quit using gacha. It's peak brainrot
I can't believe I just found your channel, you're so much better than any of the other A Level maths videos becuase they're so long and outdated. Thank you so much!
Yes understand that 😊
Too good,,, no words to appreciate.. it will be the national maths UA-cam channel for future kids
Thank you Tom! Glad you're finding them helpful..

Very clear explanations which make understanding logs and exponents a lot easier - keep up the good work
Perfect amount of examples for each segment of logs. Fuckin amazing, helped me out sm
The teacher i wish i had a school. Honestly, tysm.
I am still an AS student and I understood it thanks for the very good explanation
you're a great help
can't thank you enough
May Allah give you success in your career and make you an even better Teacher
How kind. Thank you!
the first part helped me so much! finally understand the difference between exponentials and logs
This was freakkingggg amazing.. I usually dont comment on youtube videos but urs was worth it.. Love it so much, love how you taught from the basics.. Definitely acing my exams.. thanks a ton Sarah 😍❤
Amna Asim what a lovely comment! Thank you, really glad you found it helpful! 👍
This video was sooo clear and easy to follow along with. Thank you so much 🙏
You’re most welcome, very pleased to hear that
Short, compact and crystal clear informapion, briliant!
Thank you!
I am an artist with 66 years...recently have been starting to retrieve math. Thanks
Big content covered in a short time easy to understand and follow along.Thank You!!!
Hi Frasier, thanks for your question. I'm going to be finishing the Core videos first before doing Statisitics. All the best with your exams!
+Starfish Maths Okay no worries :)
it was very good. thank you
Starfish Maths Thank you for your videos! When will you be finishing the videos?
@@isobelswann5123 it’s been 5 years lmao
what a fine teacher bless ur heart and soul
Great video, great examples and great way to explain all the laws!
Thanks a lot! :D
Thank you so much! this was really nice as it was more of a "do it yourself" to test our understanding. It was short and understandable and the questions were good, thank you a lot!
Best log video ever
Thanks for helping me but when you're making a video also in solving , make sure you teach us how to solve
oh yeah yeah
stop
Hey could you do critical regions and hypothesis testing please?
Thanks! Your videos are great
wow mam best teaching ever
Why is it not + or - on the cubed root of that equation that included subtracting the problem?
Thanks a lot..you saved my career
Thank you so much ,tomorrow is my exam and I need this
Your explanation was perfect
THANK YOU !!!!!! you save my life
Very helpful night before exam, finally understand these topics THANK YOU SO MUCH!!

At 7:26 i think t x=-2 is not a real solution because loga (-2) isn’t possible.
Beautiful and splendid teacher
Thank you very much @Starfish. Made logarithm easy for me, my add math teacher couldn’t do so
Excellent glad it helped
Ur videos was really helpful.....thank u
How do you actually find the log x and y values for the graph part
Adam Kozbar it’s a Ln graph like sort of inverse exponential funct7
Dan Best what do you mean? That’s the only part I don’t get
Thank you guys for doing a great job
Very good... understand these better. Please do more vids
Great! Yes I am doing!

Isn't 16 to the power of half equals to 8? I have done it on calculator and i got 8, and i'm getting confused how you got 4
8:42
how 81 to the power of three quarter equals to 27, on calculator i am getting 132860.25. And how 64 power half can equal to 8, isnt it 32?

same for the others: 81 to the power of three quarters, the denominator is 4, so the cubed root of 81 is 3. then square that three by the denominator (3) to get 27.
64 to the power of a half: square root of 64 is equal to 8, to the power of 1 is still 8.
hope this helps
This helped so much! Thank you!
Thank you so much
Really helpful big thumbs up 👍
I once had logarithms. I have tried not to over-confuse myself and failed ha ha ha
Please I really love your class
How could it be + or - 3/2 is it is a logarithm. Like any number with an exponential is going to be positive
you a good teacher congraturation
I can't understand the second part that clearly ☹️... I want to thoo I pm kinda getting a grip but I'm not sure. Sighhhh where can I contact you?
This is very helpful.
Thanks a bunch❤️
You're so welcome thank you
A life saver!!!!!!
pls this helped so much thank you !!
Outstanding mam👍
AMAZING THANKYOU!!
I think the negative answers should be discarded no?
Actually log(a) B a>0 and b>0 that is by Def of Logs
This was so much help thank you
proper useful. thank you so much
Really helpful material! Thank you, the videos are great. New subscriber :)
You are so underrated. Do you have any videos of entire A's CAIE board math papers solved? Thanks.
Great videos! Thank you!
10:52 but ma'm 4/10 gives 0.4
🤔 Am I Right??
it was really useful, thank you
Very helpful! Thank You!
Good 👍😊 job
3:45 But putting 1 in the place of a in
log a 1 = _
and getting
log 1 1 = 1
is also true
thanks you are great
Ur videos are amazing!
Super helpful
At 5:46 are you not meant to square root the 9 first and then divide by 4. BODMAS. Orders come first befoe division.
Even if she did square root the 9. She would have to do it to the other side of the equation to. So square root of 4 = 2 and square root of x^2 = x so she'd have 2x = 3 and then x = 3/2
no because u always do the coefficient before the power
BIDMAS only really applies when you are working out an answer and you only have one side of the equation, say: (x+6)^2 - 8 = ?
however if you have both sides of the equation already, you can do whatever you want *provided you always do the same to the other side*
Thank you🙏
How the heck I didn't found this on 2020?
really helpful
Can we get some more please :)
i have an exam tomorrow T-T thank you for your help!!!
How did it go? Glad to have helped!
@@StarfishMaths it went really well thanks!!
I understand better thank you
Very understandable to me
Logs can only be positive!
Not actually log(a) B a>0 and B>0 that is by Def
Keep it up
Thanks
great vid thanksss
I love it
half of 16 is 4?
Too good
الله ينور عليكي يا مكنه
Thankyou ! :)
thank you :)
This was really helpful, thank you very much! :-)
Thx
I like your content. Very simple and clear. And you're beautiful
"last day revision doesn't do anything"
*This video:*
Wow
yea its all good but iam still confused ....i still dont know how to solve them...maybe next time pls show more specific
How is 81¾ 27
Sorry, but you can't have negative logs. If x^2=36, x can only be 6 and not -6 too.
-6 x -6 = 36
thank you, finally someone with common sense
@@DrDagz Try plugging -6 into the equation. Any calculator will say error
Learning it for a grade 9
You're a genius babe
I do not think x = - 2 is valid in example 4.
