About This Chapter

We have short, informative video lessons to help you understand logarithmic and exponential expressions in our Exponential & Logarithmic Expressions lesson. This lesson is part of our Ohio EOCE Integrated Math I exam preparation course and study guide.

Ohio EOCE Integrated Math I: Exponential & Logarithmic Expressions - Chapter Summary

In this chapter, we'll take a look at exponential and logarithmic expressions as they may appear on the Ohio EOCE Integrated Math I exam. We'll make sure you have a solid foundation with these concepts before moving on to applying them to practice problems. Our professional instructors will help you review:

  • The definition of exponential functions
  • Defining exponential growth vs exponential decay
  • Evaluating logarithms
  • Logarithmic properties
  • Solving exponential and logarithmic equations

These short and engaging video lessons featuring professional instructors will guide you through these topics. This chapter, like the others in this course, is designed specifically with the Ohio EOCE Integrated Math I exam in mind. Thanks to our video tags, you'll have no problem jumping between concepts so you can focus on areas that you're struggling in. Once you think you know the topics, test out your knowledge with our self-assessment quizzes.

What Is an Exponential Function?

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!

Exponential Growth vs. Decay

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!

What is a Logarithm?

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!

How to Evaluate Logarithms

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.

Logarithmic Properties

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.

Practice Problems for Logarithmic Properties

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!

How to Solve Exponential Equations

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.

How to Solve Logarithmic Equations

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.
