Lesson 4 : Exponent Laws I Check it out... Can you see a short cut rule?

Exponent Law for a Product of Powers: To multiply powers with the same base, add the exponents The variable a is any integer, except 0. The variables m and n are any whole number.

Check it out..... Can you see a short cut rule?

Exponent Law for a Quotient of Powers To divide powers with the same base, subtract the exponents. a is any integer, except 0; m and n are any whole numbers.

Example 1: Simplify the following Products and quotients. ("simplify" means to combine powers and leave the answer in exponential form) Your turn...

Example 2: Evaluate the following Expressions. ( "evaluate" means to combine the powers and write your answer in standard form) Hint - use exponent laws to simplify, then evaluate. Your Turn...

Example 3: Evaluate. Use a calculator when necessary. H int: Use exponent Laws and BEDMAS Your turn...
