Precalculus A Fuctional Approach to Graphing and Problem Solving

Section 4.6: Logarithmic Equations
Problems 1-6
Use the definition of logarithms, as well as some properties to solve each equation. See Example 1.
Problems 7-16
The problems called WHAT IS WRONG?, if anything, are really enhanced true/false questions. That is, simply saying "true" or "false" is not sufficient -- you need to provide reasoning as well.
Problems 17-24
Use the definition of logarithm or properties of logarithms to evaluate the logarithms. You do not need a calculator for these problems.
Problems 25-26
These problems are exploring some ways of solving logarithmic equations.
Problems 27-30
See Example 2.
Problems 31-55
Compare each equation as one of four types shown in Example 1 to solve the equation. These problems are similar to Examples 3, 4, or 5.
Problems 56-58
Use the given equation to answer to question.
