x%5E3y%5E%28-3%29%2F%28xy%29%5E%28-1%29
We start with the denominator. Using the %28ab%29%5En+=+a%5En%2Ab%5En rule we get:
x%5E3y%5E%28-3%29%2F%28x%5E%28-1%29y%5E%28-1%29%29
Next we use the rule, a%5Em%2Fa%5En+=+a%5E%28m-n%29, we get:
x%5E%283-%28-1%29%29y%5E%28-3-%28-1%29%29
which simplifies to:
x%5E4y%5E%28-2%29
