Solve the logorithmic equation
Solve the logorithmic equation

log(8) x + log(8) (x-63) = 2

The correct answer is listed as 64.

I'm trying to learn and understand the correct way of coming down to that answer with out using a calculator. Thanks.

If I told you that $\log_8(x) + \log_8(x - 63) = \log_8(x(x - 63))$

Can you finish from there?
