# In this Section:

In this section, we learn the rules of a simplified radical. The first rule is that the radicand contains no factor other than
one that is a: perfect square - square root, perfect cube - cube root, perfect fourth - fourth root,…Essentially, this is telling us if we can remove a
rational number from the radical, we must do so to have a simplified result. Second, we learn that the radicand cannot contain any fractions. Lastly, we
are told there is no radical present in any denominator. When we are presented with a scenario that contains a radical in our denominator, we use a process
called rationalizing the denominator. This process changes the denominator from an irrational number into a rational number.
