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.)
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.)
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.
9) Simplify by factoring.
b Divide and simplify radical expressions. The Quotient Rule for Radicals For any nonnegative number a, any positive number b, and any index k, (To divide, divide the radicands. After doing this, you can sometimes simplify by taking roots.)
For any nonnegative number a, any positive number b, and any index k, (Take the kth roots of the numerator and of the denominator separately.) Divide and simplify radical expressions. b
