Warm Up Simplify each expression. 1. 2. 3. 4.

Objectives Rationalize denominators.

A quotient with a square root in the denominator is not simplified
A quotient with a square root in the denominator is not simplified. To simplify these expressions, multiply by a form of 1 to get a perfect-square radicand in the denominator. This is called rationalizing the denominator.

Directions: Simplify the quotient.

Example 1 Multiply by a form of 1 to get a perfect-square radicand in the denominator. Product Property of Square Roots. Simplify the denominator.

Example 2 Multiply by a form of 1 to get a perfect-square radicand in the denominator. Simplify the square root in denominator.

Example 3 Multiply by a form of 1 to get a perfect-square radicand in the denominator. Simplify the square root in denominator.

Example 4 Multiply by a form of 1 to get a perfect-square radicand in the denominator. Simplify the square root in denominator.

Example 5 Multiply by a form of 1 to get a perfect-square radicand in the denominator. Simplify the square root in denominator. Factor and simplify the square root in the numerator.
