## Ohio EOCE Integrated Math II: Exponentials & Logarithms - Chapter Summary

Studying for the Ohio EOCE - Integrated Math II exam can require exploring concepts you haven't reviewed in awhile. To make sure you're prepared for questions related to exponentials and logarithms, watch the entertaining video lessons in this chapter. When finished, you will be able to:

- Define an exponential function
- Differentiate between growth and decay
- Explain the meaning and how to evaluate logarithms
- Describe and solve problems related to logarithm properties
- Solve exponential and logarithmic equations

This chapter is perfect for the student who loves to study at a comfortable pace. You have the freedom to review the lessons in any sequence and at any time you desire. If you prefer your study materials in a written format, feel free to access full transcripts of the video lessons. Gauging your understanding of the lessons is also simple thanks to the short quiz available with each lesson. After utilizing these resources, you'll feel confident in your ability to address exponentials and logarithms on the exam.

### 1. What Is an Exponential Function?

Brand new technologies don't always catch on right away because they can be expensive and don't always work as well as they should. But once the price comes down, and they start to work better, it doesn't take very long before it seems like everyone has one. Learn about the numbers behind this, exponential functions!

### 2. Exponential Growth vs. Decay

How is it that it only takes four years for our computer to go from top-of-the-line to almost worthless? Well, it has something to do with what's called exponential decay, which we'll learn about here!

### 3. What is a Logarithm?

Logarithms can help you solve exponential functions. In this lesson, you will learn about how to work with and recognize logarithms, and how to use logarithm notation with an example problem about earthquakes!

### 4. How to Evaluate Logarithms

Using this lesson, you can get practice evaluating logarithms, as well as learn some of the shortcuts behind writing and estimating them. You can also learn how to use your calculator to evaluate logarithms, and learn about a concept called the change of base theory.

### 5. Logarithmic Properties

Along with the change of base property, there are three other logarithmic properties that allow you to manipulate expressions to your advantage. Learn about the product rule, quotient rule and power rule here.

### 6. Practice Problems for Logarithmic Properties

As you get further and further into mathematics, logarithms will appear more and more. It's the point of this lesson to get you used to dealing with them and able to know what to do when you see a whole line of paper full of them!

### 7. How to Solve Exponential Equations

Read this lesson to learn the steps you need to take to solve exponential equations. You'll see that it's not too difficult; you just need to make use of one other mathematical operation in order to solve your problems.

### 8. How to Solve Logarithmic Equations

If you're ever picking out a telescope to see your favorite planet, make sure you do the math first! Learn how to solve the logarithmic equation that will get you the size telescope you want.
