  2. Homework…

  3. Activity…

  4. Solving Logarithmic Equations

  5. Solve for x: Logx81=4

  6. Solve for x: ln(x -2) + ln (2x –3) = 2ln x

  7. Solve for x: ½ log5(x + 6) - log5x = 0

  8. Solve for x: log2x + log2(x + 3) = 2

  9. Solve for x: log4(x + 1) – log4 x = 1

  10. Solve for x: log(x + 1) + log x = 1

  11. Practice for QUIZ NO CALCULATOR • If log671 = 2.379, what is 62.379 ? • Simplify completely: ln e4 • Evaluate: • Evaluate: • Evaluate: log3 8110 • Evaluate: • Evaluate: • Expand: • Condense: 3[log x + log(x-2)] – ¼ log w
