Study the box below. Follow the directions and write the answer in the space provided. Rule: Examples: An exponent tells the number of times 43 = 4 . 4 . 4 Expanded form a base is multiplied by itself. 2 . 4 . 2 . 4 = 22 . 42 Exponential form 9 . 9 . 9 . 9 = 94 exponent 52 = 25 -base Simplified Write each problem in expanded form. 1. 76 3. x3 5. 89 . 9 2. 45 4. a2 . b2 6. 22 . 35 Write each problem in exponential form. 7. 5.5 10. 10 . 9 . 9 . 10 13. mon . mom 8. 11 . 11 . 11 11. 2 . 2 . 4 . 3 . 3 14. x yo x . y 9. 6 . 6 . 6 12. 3 . 2. 3 15. a . a . a Simplify each problem. 16. 72 18. 25 . 32 . 43 20. 122 + 92 17. 44+3 19. 82 . 32 21. 42 . 63 . 80Rules: Examples: To multiply powers with like bases, add the 44 . 45 = 44+5 = 49 exponents. Use the sum as the exponent with the base. 36 To divide powers with like bases, subtract the 32 = 36-2 = 34 exponents. Use the difference as the exponent with the base. 1. 23 . 25 7. 42 . 42 13. x3 . x5 2. 58 . 52 8. 92 . 9 . 93 14. m . m3 . m 3. 83 . 84 9. 3 . 34 . 33 15. 05 .
