Hi there I'm hoping a pre calc tutor can provide me some support with problems #1,9,13,17,21,23,37,47, thank you! I'm so lost
EXERCISE SET 3.4 Practice Exercises 5. 22-1 = 32 6. 32+1 = 27 Solve each exponential equation in Exercises 1-22 by expressing 7. 42-1 = 64 8. 53x-1 = 125 each side as a power of the same base and then equating exponents. 9. 321 = 8 10. 4* = 32 1. 21 = 64 2. 3* = 81 11. 9" = 27 12. 125* = 625 3. 5* = 125 4. 5* = 625 13. 31-x = 27 14. 52-* = 125 462 Chapter 3 Exponential and Logarithmic Functions 1-3 1-2 82. 3 log x = log 125 15. 6 = V6 16. 7 = V7 83. log(x + 4) - log 2 = log(5x + 1) 17. 4" = 1 1 18. 9* = - 84. log(x + 7) - log 3 = log(7x + 1) V2 V3 85. 2 log x - log 7 = log 112 19. 8*+3 = 16*-1 20. 81- = 4x+2 86. log(x - 2) + log 5 = log 100 21. ertl= 22. ex+4 = 87. log x + log(x + 3) = log 10 2x 88. log(x + 3) + log(x - 2) = log 14 Solve each exponential equation in Exercises 23-48. Express the 89. In(x - 4) + In(x + 1) = In(x - 8) solution set in terms of natural logarithms or common logarithms. Then use a calculator to obtain a decimal approximation, correct 90. logz(x - 1) - log2(x + 3) = log2() to two decimal places, for the solution. 91. In(x - 2) - In(x + 3) = In(x - 1) - In(x + 7) 23. 10* = 3.91 24. 10* = 8.07 92. In(x - 5) - In(x + 4) = In(x - 1) - In(x + 2) 25. ex = 5.7 26. ex = 0.83 27. 5* = 17 28. 19" = 143 Practice Plus 29. 5e* = 23 30. 9e* = 107 In Exercises 93-102, solve each equation. 31. 3esx = 1977 32. 4elx = 10,273 93. 52x . 54x = 125 94. 3*+2. 3* = 81 33. el-5x = 793 34. el-&x = 7957 95. 2 In x| - 6 = 0 96. 3 |log x] - 6 = 0 35. e5x-3 - 2 = 10,476 36. e4x-5 - 7 = 11,243 97. 31 = 45 98. 5* = 50 37. 7*+2 = 410 38. 5x-3 = 137 99. In(2x + 1) + In(x - 3) - 2 In x = 0 39. 70.3x = 813 40. 37 = 0.2 100. In 3 - In(x + 5) - In x = 0 41. 52x+3 = 3x-1 42. 72x+1 = 3x+2 101. 51-12 = 252x 43. e2 - 3et + 2= 0 44. e2x - 2et - 3 = 0 102. 317-12 = 92x 45. ett + 5ex - 24 = 0 46. e4x - 3e2x - 18 = 0 47. 32x + 3" - 2= 0 48. 22 + 2* - 12 = 0 Application Exercises 103. The formula A = 37.3e0.00 models the population of Solve each logarithmic equation in Exercises 49-92. Be sure to California, A, in millions, t years after 2010. reject any value of x that is not in the domain of the original
