8-1 Multiplying Monomials Objectives SWBAT: 1) multiply monomials 2) Simplify expressions involving powers of monomials

Monomials A monomial is a number, a variable, or a product of a number and one or more variables Examples:

Example 1: Write each product in expanded form and write as a single power. What do you notice?

Product of Powers To multiply two powers that have the same base, add the exponents.

Example 2: Simplify each expression.

Example 3: Find the power of each power by writing each in expanded form. Write your answer as a single power. What do you notice?

Power of a Power To find the power of a power, multiply the exponents.
