Question

If (2^x)(2^-4x) = 1/8, then x = ?

Answer 1

need help

Answer 2

x=\[2^{-3x}=2^{-3}, x=1\]

Answer 3

did u got answer

Answer 4

the left simplifies to 2^(-3x)
and the right can be rewritten as 2^(-3)
so its
2^(-3x)=2^(-3)
so x=1

Answer 5

yes it is but i not really understand. Is it 1/2^3 = 1/8 so x = 1?

Answer 6

1/2^-3x=1/8 so x = 1?

Answer 7

yes

Answer 8

ok I understand now. Thanks
