**
For one-term radicals in the denominator, multiply top and bottom by the radical itself.
For two-term radicals in the denominator, multiply top and bottom by the conjugate to get a difference of two squares to eliminate the radicals.
Remember, we only talking about radicals with index of 2 or square roots. To rationalize terms with radicals of other than index 2, a different method is required.
