Rationalizing Denominators in Radicals

Rationalizing Denominators in Radicals. Sometimes we would like a radical expression to be written in such a way that there is no radical in the denominator. To achieve this goal we use a process called rationalizing the denominator. Multiply both numerator and denominator by.
