6-22

6-22 Practice Exercises 15. 64 = V6 16. 76 = V7
Practice Exercises 15. 64 = V6 16. 76 = V7 Solve each exponential equation in Exercises 1-22 by expressing each side as a power of the same base and then 17. 4* = 18. 97 = 13/3 equating exponents. V2 1. 2* = 64 . 2. 3* = 81 19. 8x+3 = 16x-1 20. 81 -x = 48+2 3. 5* = 125 4. 5* = 625 21. extl - 22. ext4 - H / 2 5. 22x-1 = 32 6. 32x+1 = 27 7. 42x-1 = 64 8. 53x-1 = 125 Solve each exponential equation in Exercises 23-48. 9. 32* = 8 10. 4x = 32 solution set in terms of natural logarithms. Then use to obtain a decimal approximation, correct to two de 11 97 = 27 12. 125% = 625 for the solution. 13. 31 -* = = 14. 52-* = 125 23. 10* = 3.91 24. 10* = 8.07
