I’m so sorry to trouble you but I urgently need some maths help. All working must be shown also.
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,
Tara

well, here are some reviews:

$a^na^m = a^{n+m}$
$(a^n)^m = a^{nm}$
$1 \div a = \dfrac{1}{a}$ and so $1 \div a^n = \dfrac{1}{a^n}$

combine these, you must get the answers..
