College Algebra: Rationalizing Denominators

This lesson is part of a series: College Algebra In this lesson, you will learn how to get square roots (or cube or other roots for that matter) out of the denominator of a fraction without changing the mathematical value of the fraction. This process is called 'Rationalizing' the denominator. Mathematicians agree that proper fractions should not have radical signs in the denominator, so when you end up with an answer that has a radical in the denominator, it is best to rationalize (as your answer will be marked wrong or will not appear as a choice if you do not). Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive course, College Algebra. This course and others are available from Thinkwell, Inc. The full course can be found at http://www.thinkwell.com/stude... The full course covers equations and inequalities, relations and functions, polynomial and rational functions, exponential and logarithmic functions, systems of equations, conic sections and a variety of other AP algebra, advanced algebra and Algebra II topics. Founded in 1997, Thinkwell has succeeded in creating a "next-generation" textbook, one that helps students learn and teachers teach.
