Students will: Write expressions using Negative Exponents Evaluate numerical expressions containing negative exponents You will need pencil, paper and math textbook

Negative Exponent Positive Exponent

Negative Exponent Positive Exponent

Expanded Form Standard Form 10 = 10 x 10 x 10 1,000 10 = 10 x 10 100 10 = 10 10 10 1 10 Dividing by 10

Copy these two examples Method 1 Quotient of Powers Method 2 Definition of Power Since cannot have two different values, you can conclude that

Example 1 Write as Positive Exponents

We have to know how to write exponents as positive and negative and go from one to the other

Example 2: Use Negative Exponents 7. 8. 9. 10
