*PLEASE ANSWER AS SOON AS POSSIBLE BRO!!!!!! :) =) BTW, you are supposed to somehow express in terms of u, and not solve it with a calulator. :) Found 2 solutions by Big Poop, josmiceli:Answer by Big Poop(157) (Show Source):
You can put this solution on YOUR website! given:
(1)
I will say that:
(2)
Now the problem is to find in terms of
I will take the th root of both sides of (2)
(2)
(2)
--------------
Now I will raise each side of (2) to the power
(2)
but,
(1)
so,
take log base 2 of both sides
This is the best I can do, because if I do the
substitution , then just
gets eliminated from the equation.
-------------------------------
check answer using my Casio fx-115ES
I'll pick any value for , like
(1)
(1)
Take log base 9 of both sides
(1)
(1)
and
so close enough
