Bell Quiz
Objectives
• Learn to simplify expressions by using three new properties for exponents: – The Power of a Power Property– The Power of a Product Property – The Power of a Quotient Property
Properties for Exponents
• Previous lessons have explored expressions involving exponents.
• Several rules and definitions have been developed.
Properties for Exponents
• There is another property of exponents that involves raising a power to a power.
Example 1Simplifying a Power of a Power
