Front

What is 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 product of two radical expressions?

Back

To multiply two radical expressions, multiply the numbers outside the radicals and the numbers inside the radicals separately. For example, @@ oot{m}{a} imes oot{n}{b} = oot{mn}{ab}@@.

What is the quotient of two radical expressions?

Back

To divide two radical expressions, divide the numbers outside the radicals and the numbers inside the radicals separately. For example, @@rac{ oot{m}{a}}{ oot{n}{b}} = oot{m}{rac{a}{b}}@@.
