  1. The “Natural” Log Objective: solve natural log equations; simplify natural log expressions using properties How is the natural log different from the common log?

  2. The Natural Log • Notation: ln( ) • Base: e • Same rules/properties as log

  3. The number “e” • The number the formula approaches as the number of “compounds” increases

  4. Ex 1) “Swoosh” & Solve ln(x – 1) = -2 1.135

  5. Ex 2) Solve for x 12

  6. Ex 3) Solve using the natural log 1.609

  7. ln(2x-3) = 2.5 7.591

  8. ln(5) + ln(x) = 4 10.92

  9. ln(2x) + ln(3x) = ln 6 1

  10. Solve using the natural log 3.136

  11. Solve using the natural log .49

  12. Solve using natural log 1.099

  13. Solve using the natural log -.588
