No matter i did it, can't express both side as a power with base 2

Here is the equation: cubic root(256^{2}) * 16^{x}=64^{x-3}

I need to express both sides as a power with base 2, but no matter how i solve it, it never can make base 2.

HELP!!

Hey JarvisStu001.

Hint: Recall that 16 = 2^4 and 64 = 2^6 with the fact (a^xy) = (a^x)^y.

You need to awake up to basic powers.
