In order to divide radical expressions, we must simplify them. So knowing tools for simplifying radical expressions is key to dividing them.

The most important tool for dividing radical expressions is the quotient property of square roots.

This property states that √a / √b =√(a/b).

The quotient property of square roots can be used when simplifying or performing operations like division in radical expressions.

Specifically, √a / √b = √(a/b) can be used when a and b are not perfect squares and a/b is a rational number.

Also, √(a/b) = √a / √b can be used when a/b is not a perfect square, but separately a and b are rational numbers.

It is important to remember that the final result of dividing radical expressions must be in simplest radical form as well.

This video will show examples that explain how to use the quotient property of square roots for division of radical expressions.
