3. 2/5/16 Lesson 6 – 4 Log & Exponential Equations Day 1 Advanced Math/Trig

4. Learning Objective To solve log equations To solve exponential equations

5. Solve Write left side as a single log. 9x – 6 = 4(x + 1) 9x – 6 = 4x + 4 5x = 10 x = 2 MUST CHECK IN ORIGIANL EQUATION!! CANNOT LOG (–)

6. Solve x = 0 or 4 MUST CHECK IN ORIGIANL EQUATION!! CANNOT LOG 0! x = 4

7. Solve MUST CHECK IN ORIGIANL EQUATION!! CANNOT LOG (–)! (3x – 1)(x – 6) = 0 x = 6

8. Special Log Rules

9. Evaluate

10. Logarithm

11. Solve for x Can’t write as same base  Log both sides Use Properties Get variables on one side Factor out x Divde

12. Solve for x

15. Change of Base Formula

16. Evaluate Calc Ready

17. Evaluate

18. Ticket Out the Door Solve for x log(5x) + log(6x + 1) = 1
