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

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
