Im almost done but im stuck with the exponent, im trying to solve for r: A/B=r^(1-n). How do i get the exponent on the other side? Thank you.

You have to calculate an exponent (= logarithm). Probably you now know how to do this question: $\displaystyle r^{n-1} = \dfrac AB~\implies~ n-1 = \log_r\left(\dfrac AB \right)$ I'll leave the rest for you.
