((x^(3/2))y^-3)^1/3
        --------------------
        ((x^(1/2))y^-6)^-1

Start with the given expression.


Distribute the outer exponents to the inner exponents. Remember, . So in our case the numerator goes from to and the denominator goes from to


Use the technique described above to distribute the exponents.


Multiply the exponents.


Reduce.



Now when we divide monomials, we simply subtract the exponents. So for example

Let's apply this technique to the problem:

Subtract the exponents.

Rewrite as


Combine the exponents.


Reduce.


Simplify


Now rewrite as



So simplifies to

In other words, where every variable is positive and or
