I wasn't sure exactly were to post this because its actually apart of a logarithm i'm trying to do,
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 >_<
This should help you. 7 is the coeffecient of 7z^3, z is the base. 7 would be the base of 7^1, which it is. Therefore, the base of z^2 is z. So the base is still the same, z. I know someone else has answered this, but maybe my explanation will help you out as well, after all there are many ways to skin a cat.
