  1. 6.3 Simplifying Radical Expressions

  2. a Multiply and simplify radical expressions. The Product Rule for Radicals For any nonnegative real numbers a and b and any index k, (To multiply, multiply the radicands.)

  3. Multiply and simplify radical expressions.

  4. 5) Multiply and simplify radical expressions.

  5. a Multiply and simplify radical expressions. Factoring Radical Expressions For any nonnegative real numbers a and b and any index k, (Take the kth root of each factor separately.)

  6. a Multiply and simplify radical expressions. Simplifying kth Roots To simplify a radical expression by factoring: 1. Look for the largest factors of the radicand that are perfect kth powers (where k is the index). 2. Then take the kth root of the resulting factors. 3. A radical expression, with index k, is simplified when its radicand has no factors that are perfect kth powers.

  7. Multiply and simplify radical expressions.

  8. 9) Simplify by factoring.
