I know this is probably the easiest problem in the review questions, and it’s the only one I can’t solve... I’m feeling a tad stupid right now. Any help would be greatly appreciated.
Thankyou for your help,

well, here are some reviews:
$\displaystyle a^na^m = a^{n+m}$
$\displaystyle (a^n)^m = a^{nm}$
$\displaystyle 1 \div a = \dfrac{1}{a}$ and so $\displaystyle 1 \div a^n = \dfrac{1}{a^n}$
combine these, you must get the answers..
