Simplifying and
Multiply and simplify two products of square roots whose radicands contain both numbers and variables.
ⓐ :
Apply the Product Property to combine the radicands under a single radical:
The numerical coefficient and the variable part (add the exponents: ). Now simplify the radical by extracting the largest perfect square factor. The largest perfect square dividing is , and is already a perfect square:
The simplified result is .
ⓑ :
Combine the radicands under a single radical:
The coefficient is a perfect square, and the variable has an odd exponent. Factor the largest perfect square: :
The simplified result is . These examples extend the technique of multiplying square roots to radicands that include variables — after combining under one radical, the Product Property for Exponents determines the new variable power, and then the standard simplification procedure extracts all perfect square factors.
