Lesson 9.4 Page 500 Negative Exponents

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

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

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