Chapter 13  Exponential and Logarithmic Equations
"In this chapter, students use their understanding of exponential and logarithmic functions to solve exponential and logarithmic equations. Students begin by building understanding and fluency with exponential and logarithmic expressions, including estimating the values of logarithms on a number line and then use this understanding to derive the properties of logarithms. Students explore alternative methods for solving logarithmic equations and solve exponential and logarithmic equations in context." Carnegie Textbook 
"Logarithmic equations can be used to describe the intensity of sounds and the amount of medication in a patient’s bloodstream. They can even be used to help solve crimes!"  Carnegie Textbook

Lesson 13.1 Exponential and Logarithmic Forms
"Students convert between exponential and logarithmic equations, estimate the values of logarithmic expressions with different bases, and solve simple exponential and logarithmic equations."  Carnegie Textbook Lesson 13.2  Properties of Logarithms
"In this lesson, students derive the Zero Property, the Product Rule, the Quotient Rule, and the Power Rule of Logarithms and identify the value of a logarithm with the same base and argument."  Carnegie Textbook 
Lesson 13.3  Solving Exponential Equations
"Students derive the Change of Base Formula and use this formula as a strategy to solve exponential equations. Students also explore taking the logarithm of both sides of an equation to solve it."  Carnegie Textbook Lesson 13.4  Solving Logarithmic Equations
"In this lesson, students solve logarithmic equations for different unknowns—base, argument, or exponent using the strategies and properties they have learned in previous lessons."  Carnegie Textbook Lesson 13.5  Applications of Exponential and Logarithmic Equations
"In this lesson, students use exponential and logarithmic models to solve problems involving logarithmic equations."  Carnegie Textbook
