Transcript of Division of numbers in exponential form
HOUSEKEEPING
Yesterday we looked at the multiplication property of exponents. You learned that when multiplying powers with the same bases, you simply add the exponents.
Today & Friday – MAP testing 9:00 am or 2:00 pm
PROPERTIES OF EXPONENTS

GOAL FOR TODAY…….
Goal: Be able to apply
properties of exponents to generate equivalent numerical expressions
