  3. Agenda • Get quiz back. • Work review problems from the board. (Turn them in at the end of class.) • Test tomorrow!!!!

  4. 1 Solve. 52x = 59x + 7 x = -1

  5. 2 Solve. x = -2, 5

  6. 3 Solve. x = 1 6

  7. 4 Solve. 27x = 800 x = ?

  8. 5 Solve. logx 512 = 3 x = 8

  9. 6 Solve. log8 (3x - 6) = log8 (9x + 23)

  10. 7 Solve. log7 (x2 - 5) = log7 (59)

  11. 8 Solve. log9(x + 3) = log92x x = ?

  12. 9 Solve. Round to 4 decimal places. 3x = 72 x = 3.8928
