Rules for Dividing Radicals 1)

Rationalizing the Denominator The rules for simplest radical form state that we cannot leave a radical in the denominator of a fraction. So, how do we get rid of a radical that is not a perfect square or does not simplify itself out? The Power of 1: We simply multiply the numerator and denominator by the radical found in the denominator and then simplify what remains if necessary.
