1. 10.2 Logarithms and Logarithmic functions

2. Graphs of a Logarithmic function verse Exponential functions In RED y = 10x , In Blue y = Log x The functions relate in which way?

3. The Main Concept of Logarithms Remember the way an exponential function and a Logarithm function is related.

4. The Main Concept Remember

5. Write in Exponential form Log 4 16 = 2

6. Write in Exponential form Log 4 16 = 2

7. Write in Logarithmic form 53 = 125

8. Write in Logarithmic form 53 = 125

9. Use the concept Solve
