The video tutorial explains how to multiply and simplify radical expressions. It begins by introducing the concept of multiplying radicals and demonstrates that the product of two square roots can be combined under a single radical. The tutorial then focuses on simplifying the resulting expression using square numbers, identifying the largest square number that divides the product, and rewriting the expression accordingly. The process concludes with the simplification of the expression by recognizing perfect squares and leaving non-perfect squares as they are.

What is the basic rule for multiplying two radical expressions?

• Divide the numbers under the radicals.

• Subtract the numbers under the radicals.

• Multiply the numbers under the radicals.

• Add the numbers under the radicals.
