Simplify the expression

Let's start with the most simple thing: we know that anything to the power of 0 is 1, so we change that. This gives us: 

r^-1(s^-1) /r^-3(s)(q)(s)

from here, we can see that r^-1 is 1/r, same with the s^-1, and r^-3 is 1/r^3. So, plug that in:

1/r(1/s)/(1/r^3)(s)(q)(s)

(1/rs)/(s^2*q/r^3)

Finaly, we divide.

You should get r^2/qs^3
