2. Read page 345 and answer questions 1-4 in your groups
A common logarithm is the exponent that ten must be raised to in order to get 10y
In other words
Try problems 5 and 6 in your groups
We will do a and b for each one together

3. Read example 3 on page 348 and do problems 7, 8, and 9
Be sure to make note of the properties listed on page 349
The natural logarithm (or natural log) is used when the base is the number e
It has all the same properties of logarithms
Is used often because e is the natural base used in many exponential functions
Read example 4 on page 349 and complete problem 10 in your groups
Read the next paragraph and look at example 5
Complete problem 11 (we will do a and b together)
If you finish early do problems 12 and 13
