The bit thats troubling me is I have to divide
7z^3 by z^2
(I just using ^ for a 'power of' symbol)
Now I know when dividing powers of the same base you simple take them away from each other e.g. 3 - 2
But the fact that the first number is 7z and the second is just z are they still the same base? can I apply this theory?
Help greatly appreciated, got an exam next Monday >_<
