he should make a video proving why substitution is powerful and how/when to use it
Yeah definitely
It is an interesting (and somehow easy) equation. Thanks!
Np
I used natural log to take out the powers, divided both sides by ln10 and used a formula for transitioning to a new base and arrived at the same quadratic you had, Vieta's theorem to solved for logx and solve for x.
Seems to be adding unnecessary complication to use ln when the whole expression is already using base 10.
Got 'em both!
has a cool idea...👌👌👌.Thanks...🙏🙏🙏.
Thank you!
Nice and easy!!!❤❤❤i used the first method
Great! ❤
x = 10
Beautifil thinking and analysis on method #2. I did it applying log both sides, but now I feel more robotic after seeing method #2. Thanks!
As always good🙂
Thanks
x=10, 1/10000
log x= 1 or -4x=10 or 1/10000
7:46 what was it again？ 10X did you say？
10x yup it happens
