Q1. Solve: log9x - log3x = 0
Q2. Solve: log2(x + 1) - log4x = 1
CORRECTION: Alternate Method around 5:33: It should have been log(1/x) = 1, and then x = 1.
Thanks to our subscriber for the feedback.

I loved the way you do an analogy of both nature and maths as yes they are two faces of the same coin ❤❤

With my cellphone I am unable to manipulate base. On paper I can show you my method without any confusion. Life is simple, maths is simple. We complicate them. Nothing wrong with your method

wasn't the last line supposed to be log(3)x -2log(3)x-log(3)x ?

In 2nd example, you have solved x²-2x+1=0 directly to (x-1)², but the same can be factorized and we can get the factors by x²-2x+1x+1 to x=2 and x=-1 So is this incorrect??

@MathematicsTutor
@MathematicsTutor 4 года назад
denominator log3(3^2) = 2log3(3) = 2 This results into 1/2 Thanks

Here is alternate way to describe: denominator is log(3) 3^2 -- log to the base of 3 log(3) denominator is log(3) 3^2 = 2 log(3) 3 = 2(1) so you get 2 in the denominator. Let me know if that is clear. Thanks

What if log has addition inside the base? "If Log to the base a+2 of 7 < 0 (a is an integer), then a belongs to the interval:?" My math teacher won't teach me how to solve this until whole class joins logarithm concept 😭 (I'm ahead of others)

greetings sir: On timeline 5:33, how can log base 3 of x/x^2 =x? Should that not equal log base 3 of 1/x?
@MathematicsTutor

Thanks, You are right. It should have been log(1/x) = 1, and then x = 1.

You are solving test questions. So, the concepts should be clear to you. Change of base should be absolutely clear. You may check my playlist on the same and then make your judgement. Here is a Playlist: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-M296r1ys4jc.html Thanks
