Question

solve 8^(y - 3) = 2^y

Answer 1

polynomials again? :D

Answer 2

yes :P

Answer 3

would you like the real or alternative solution? :3

Answer 4

the answer haha i'm so lost...

Answer 5

\[8^{(y-3)}= 2^{y}\]
the idea is to have the same base:
\[2^{3(y-3)} =2^{y}\]
3(y-3) = y
3y-9 = y
solve for y

Answer 6

(8^y)(8^-3)=2^y
8^y * -24 =2^y
-8^y =-8^y
-24= -6^y
-24/-6
4=y
