How do you multiply two radicals? To multiply two radicals, multiply the numbers inside the radicals (the radicands) and leave the radicals unchanged. √a x √b = √(a x b) We just have to rewrite the coefficient with an exponent that includes the common factor of the exponents, and then reduce the radical as usual. Example 10.5.3. Reduce: 8m6n3− −−−−√9 8 m 6 n 3 9. Solution. First, we’ll need to rewrite the coefficient 8 8 with an exponent that includes the common factor of the exponents.To simplify radicals like √12, we will use the following 3-step strategy: Step One: List all of the factors of the number inside of the radical. Step Two: Determine if any of the factors are perfect squares (not including 1). If there are multiple perfect squares, choose the largest one.A radical expression is simplified if its radicand does not contain any factors that can be written as perfect powers of the index. We typically assume that all variable expressions within the radical are nonnegative.
