4^y=64^13. solve for Y. the answer is 39, but I got a way different one. Where did I go wrong? How do I solve it?

Answer 1

show your work, please

Answer 2

First, you want to make your bases the same.
\[4^y=(4^3)^{13}\]
\[y=3 \times 13\]

Answer 3

That makes sense, for some reason I was trying to multiply 4 by 16 which turned out to be a lot more confusing! Thank you monokerous!
