5.4 Logarithmic Functions if b called the base of the logarithm when asked to evaluate a logarithm, your answer is the exponent of b that equals x.

Properties Logarithmic Functions

Example 1: Evaluate Logarithms Evaluate the following: The base to what power equals x???

Common and Natural Logarithms Two types of logarithms are written without the bases. You will be expected to remember what the base is based on the notation. These can be solved using your calculator. Common Logarithm: Natural Logarithm:

Example 2: Evaluate Logarithms Evaluate the following: The base 10 or e to what power equals x???

Example 3: Solving Logarithmic Equations Solve by rewriting in exponential form:
