Solving Log Function
Okay, so I have to find x in the log equation. Please don't just tell me the answer, I need an explanation and what I'm doing wrong. (Worried)

log4(x+2)-log4(x-3)=2

I've tried dividing (x+2) and (x+3) since they have the same base, and then setting it equal to 2. But I can never get the right answer!!!!

Re: Solving Log Function
$\log_4(x+2) - \log_4(x-3) = 2$

$\log_4\left(\frac{x+2}{x-3}\right) = 2$

change to an exponential equation ...

$\frac{x+2}{x-3} = 4^2$

finish it
