In Lesson 3.1, the emphasis was on simplifying radicals by removing the perfect \(n^{th}\) root factors from the radicand, where possible. Removing radicals from the denominator of rational expressions is another simplification process. The following sections focus on this step, first by investigating addition, subtraction, multiplication, and division with radicals, and ending with the process of
rationalizing the denominator.
