  1. log b 2 = 0.3562 log b 3 = 0.5646 If , and , evaluate each expression. 1. 2. 3. 4. log b5 = 0.8271 log b log b 30 log b 0.024 log b 128

  2. 1. Convert log61296 = 4 to exponential form. 64 = 1296 2. Convert 43 = 64 to logarithmic form. log464 = 3

  3. Solve the equation using the properties of logarithms. 3. logx125 = 3 4. log324 – log3x = log36 x3 = 125 log3 = log36 x = 5 = 6 x = 4

  4. Evaluate using a calculator. 5. log 15 6. antilog 0.3894 7. ln 3(2)4 3.8712 2.4513 1.1761

  5. 8. Use the change of base formula to evaluate. log5314 = 3.5723 log820 = 3x 9. Solve 83x = 20 = 3x x = 0.4802
