Front

Define a radical expression.

Back

A radical expression is an expression that includes a root, such as a square root, cube root, etc. For example, @@ ext{radical expression} = ext{ } oot{n}{x}@@.

What is the quotient property of square roots?

Back

The quotient property states that @@ oot{2}{rac{a}{b}} = rac{ oot{2}{a}}{ oot{2}{b}}@@.
