# Algebra 1 Simplify Rational Exponents

Section 11: Radical Equations: Lecture 2 | 15:12 min

In this lesson we are going to look at simplifying rational exponents. The things we will look at are the product rule, the quotient rule and what to do when they involve radicals. To simplify radical expressions, we often split up the root over factors. If we are working with a square root, then we split it up over perfect squares. You'll learn how you can use the quotient rule to split up radicals over division. This lesson also covers the applications of product and quotient rules, as well as higher roots.
