Simplifying and Multiplying Radicals Mastery

This video tutorial covers simplifying, multiplying, and dividing radical expressions. It begins with a review of terminology related to radicals, such as perfect squares and radicands. The video then explains how to simplify radical expressions by identifying the largest perfect square factor of the radicand. Several examples are provided to illustrate the process. Alternative methods for simplification are also discussed. The tutorial concludes with a section on multiplying radical expressions, including step-by-step examples.

What are perfect squares?

• Numbers that can be divided by 2

• Numbers whose square roots are integers

• Numbers that are multiples of 10

• Numbers that cannot be simplified

What does the radicand refer to in a radical expression?

• The exponent within the radical

• The coefficient outside the radical

• The expression under the radical sign

• The base number of the radical

How do you multiply radical expressions?

• Add the coefficients and multiply the radicands

• Multiply coefficients outside and radicands inside separately

• Multiply everything inside the radical first

• Multiply the radicands and add the indices
