1. CONVERTING FROM ONE FORM TO ANOTHER EVALUATING PROPERTIES OF LOGS – EXPANDING AND CONDENSING Day 1:

2. Learning Targets – Unit 6 I can expand and condense logarithms I can solve log and exponential equations I can convert from logs to exponentials I can solve word problems with log and exponential equations I can find the shape of a regression and determine which regression equation to use I can use my calculator to find the regression equation I can solve word problems using regression equations

3. What do we need to do to keep improving?

4. Practice: Write each in log form. 1. 5 4 = 625 2. 64 = 8² 3.

5. Write into exponential form: 4. log 2 128 = 7 5. log 6 6 = 1 6. log 2 =-1

6. Evaluating Logarithms: Change of base formula. 7. log 8 16. 8. log 64 9. log 9 27 10. log 100

7. Properties of Logarithms Product property : Quotient Property: Power Property:

8. Properties of Logarithms Product property : Quotient Property: Power Property: Expand: 1. 2.

9. Expand: 1. 2. 3.

10. Write as a single log: 1. log 7 + log 2 2. log 5 – k log 2 3. log 6 5 + log 6 x 4. 4 log m – log n

11. Evaluate: 1. log 1 + log 100 2. 3 log 2 2 – log 2 4 3. log 6 4 + log 6 9 4.
