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
