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}@@.

Front

How do you simplify a radical expression like @@ ext{ } oot{n}{a imes b}@@?

Back

To simplify, you can separate the radical: @@ ext{ } oot{n}{a imes b} = oot{n}{a} imes oot{n}{b}@@.

Front

What is the simplified form of @@ ext{ } oot{n}{rac{a}{b}}@@?

Back

The simplified form is @@rac{ oot{n}{a}}{ oot{n}{b}}@@.

Front

What is the value of @@ ext{ } oot{4}{16}@@?

Back

The value is 2, since 2 raised to the power of 4 equals 16.
