In math, we aim to leave all denominators rational, meaning your final expressions shouldn't have any roots in the bottom of a fraction. If there is a root, you "rationalize the denominator" by multiplying top and bottom of the fraction by that root which is really just multiplying by one. The same is true if your numerator is a binomial. You could choose to reduce the roots before or after the multiplication you should get the same answer either way.
