In simplifying expressions like this, it is often helpful to replace radicals with fractional exponents. So this is where we'll start:
Now we can start using our rules and properties of exponents. In the denominator we can use the property, :
Then we can use the power of a power rule (i.e. multiply the exponents):
Reducing the fractions we get:
Now we'll use the rule for exponents when dividing (i.e. subtract the exponents):
To subtract the exponents we need the same denominators:
which simplifies to:
which may be an acceptable answer. But we could also do the following:
(
