Rules for Writing Radicals

When writing expressions with radicals, follow these key rules:

Use the radical symbol (√) for square roots and other roots.
Simplify radicals by removing perfect square factors from the radicand.
Combine like radicals by adding or subtracting their coefficients.
Rationalize denominators by eliminating radicals from the denominator.

√(a·b) = √a · √b √(a/b) = √a / √b √(a^n) = a^(n/2) when n is even

Examples of Radical Expressions

Here are some examples of expressions written as radical expressions:

Example 1

Convert x^(3/2) to radical form:

Solution: x^(3/2) = x·√x

Example 2

Convert √(18) to simplest radical form:

Solution: √(18) = √(9·2) = 3√2

Frequently Asked Questions

What is a radical expression?

A radical expression is a mathematical expression that includes a radical symbol (√) and a radicand (the number under the radical). Radical expressions can represent roots of numbers.

How do I simplify a radical expression?

To simplify a radical expression, factor the radicand into perfect squares and separate the square roots of each factor. Combine like terms and simplify the expression.

Can I use this calculator for cube roots?

Yes, this calculator can handle cube roots and other roots by converting exponents to radical form. Enter the expression with the appropriate exponent for the root you need.
