Simplifying and
Multiply and simplify products of radicals that have numerical coefficients and variable radicands.
ⓐ : Multiply the coefficients together and the radicands together: Simplify the resulting radical by extracting the largest perfect square factor (): Simplify the perfect square and multiply it with the outside coefficient:
ⓑ : Multiply the coefficients and the radicands: When the radicands involve large numbers, it is often advantageous to factor them to find perfect powers (). Identify the largest perfect fourth power factors: Simplify the perfect fourth power and multiply:
