3.4 - nth Roots and Radical Expressions

Author: Kyle Webb

Operations of Radical Expressions

We will need to remember these two basic properties of radicals.

Product Property of Radicals

$n-th root of a b end root equals n-th root of a cross times n-th root of b$

Quotient Property of Radicals

$n-th root of a over b end root equals fraction numerator n-th root of a over denominator n-th root of b end fraction$ , as long as all roots are defined and $b not equal to 0$
