Question

Someone wanna help me out? 2^(4x+2)=8^(x-3)

Answer 1

Hint: logarithms

Answer 2

log two of both sides gives
4x+2 = (x-3)log_2(8)
so 4x+2 = 3(x-3)

Answer 3

do you see why?

Answer 4

when I write log I mean log base 2

log(2^(4x+2)) = (4x+2)log(2) = 4x+2

Answer 5

-_- Im retarded. Yeah, I got -11

Answer 6

and on the rhs
log(8^(x-3))
= (x-3)log(8)
now 2^? = 8
3
so 3(x-3)
