This lesson covers simplifying radical expressions using the product and quotient properties of square roots. It explains how to simplify radicals with variables and rationalize denominators using conjugates. The video provides examples and encourages students to practice these techniques independently.

What is the product property of square roots?

• The square root of a quotient is the quotient of the square roots.

• The square root of a product is the product of the square roots.

• The square root of a sum is the sum of the square roots.

• The square root of a difference is the difference of the square roots.
