1. Logarithms

2. What is a LOGARITHM? • A logarithm is another way to represent an exponent. • Video

3. Switch answer and exponent Drop the Drop the base Drop the

4. Try These- Rewrite as Logarithms Log381 = x • = 81 • = x • = 128 Can you solve for x? Log4x = 5 Logx128 = 7

5. Try These- Rewrite as Exponents • Log5x=2 • Log464=x • Logx49=2 Can you solve for x?

6. Can you think of another irrational number that has its own symbol? Can you find e on your calculator? Pi π ~ 3.14

7. Try These logx = 4 • = x • = 5 • log 1000 = 3 • ln 7 = x ln 5 = x = 1,000 = 7

8. Assignment • Handout Circles worksheet. • Look at each exponential and logarithmic equation. • Shade each matching pair the same color or pattern. • Practice QUIZ
