+ Using Properties of Exponents EQ: How do we use properties of exponents? M2 Unit 5a: Day 1 Wednesday, October 07, 2015

+ Properties of Exponents Let a and b be real numbers and let m and n be integers. Product of Powers Property Power of a Power Property Power of a Product Property Zero Exponent Property Quotient of Powers Property Power of Quotient Property Negative Exponent Property

+ Product of Powers: Examples: a. b. To multiply powers with the same base, add the exponents and keep the common base.

+ Your turn: Keep common bases Add the exponents

+ Power of a Power: Examples: a. b. To raise a power to a power, keep the base and multiply the exponents.

+ Your turn: Keep The Base Multiply The Exponents

+ Power of a Product: Examples: a. b. To raise a product to a power, raise each factor to the power. This should remind you of the distributive property. Remember to “distribute” the exponent to each base, numeric and variable! Warning: No distributing over addition!!! Simplify any numeric bases raised to exponents

+ Your turn: Raise Each Factor To The Power It’s Like The Distributive Property

+ Zero Exponent: Examples: a. b. Any number raised to the zero power is equal to “1”.

+ Your turn: Anything Raised To The Zero Power =1

+ Quotient of Powers: Examples: a. b. To divide powers with the same base, subtract the exponents and keep the common base. Also, remember that common factors cancel out! Keep the base where the exponent is larger

+ Your turn: Common Factors Cancel Out With Common Bases Subtract Exponents

+ Power of Quotient: Examples: a. b. To raise a quotient to a power, raise the numerator and the denominator to the power.

+ Your turn: Raise the numerator and denominator to the power Simplify any factors with numeric bases

+ You may want to think of it this way: unhappy ( ) exponents will become happy ( ) by having the base/exponent pair “switch floors”! Example: A.) B.) Negative Exponent Property:

+ You try:

+ Simplifying Exponential Expressions To simplify exponential expressions completely:  Get rid of parentheses  Get rid of negative exponents  Make sure there is only one of each base  Cancel out common factors
