7­2 Division Properties of Exponents

Learning Targets:I can divide monomials using the properties of exponents

I can simplify expressions containing negative and zero exponents

What is 102 when simplified?

What is 101 when simplified?

How could you use exponents to write the ratio of the height of a skyscraper that is 900 meters tall to the height of the tallest tree?

Zero exponent: any nonzero number raised to the 0  power.

Any number divided by itself is 1, any number divided by itself has a 0 exponent.
