6. 9.3 Simplifying Radicals Goal Simplify radical expressions Key Words Radical Simplest form of a radical expression Product property of radicals Quotient property of radicals

7. 9.3 Simplifying Radicals The simplest form of a radical expression is an expression that has no perfect square factors other than 1 in the radicand, no fractions in the radicand, and no radicals in the denominator of a fraction. Properties of radicals can be used to simplify expression that contain radicals.
