Presentation transcript:

Division Properties of Exponents Simplify expressions involving quotients of monomials , and to simplify expressions containing negative exponents.

Exploration: Rule: You can cancel pieces that are the same on the top and bottom of a fraction because when you divide them they equal 1!! 1 1 1

Exploration: Rule: When dividing exponents: keep the base the same and subtract the exponents! *If you get a negative exponent it goes on the bottom!!
