These video lessons last about five minutes on average and are available anytime, on computer, tablet or smartphone. Short quizzes follow each lesson, and let you assess your learning. Other useful features include a written lesson transcript with important vocabulary and concepts in bold type and a clickable Timeline with links back to key points in the lesson video.

NES Math: Exponents & Exponential Expressions Chapter Objectives

Passing the NES Math test is one of the requirements for certification to teach math at the secondary level in five states. The test's questions are divided into content domains, and questions on exponents and exponential expressions are in the Patterns, Algebra and Functions content domain. This is the largest content domain on the test, making up 24% of the scoring.

All NES Math test questions are multiple-choice, and the test is computer-delivered. Our quizzes are also in this format, so completing them offers experience with these types of questions, in addition to an assessment of you learning.

7 Lessons in Chapter 10: NES Math: Exponents & Exponential Expressions
Exponential Expressions & The Order of Operations

1. Exponential Expressions & The Order of Operations

When performing mathematical operations, there is a specific order in which the operations should be performed. This includes when to simplify the exponents. This lesson will describe in what order exponents should be solved as you are performing mathematical operations.

What Are the Five Main Exponent Properties?

2. What Are the Five Main Exponent Properties?

We'll look at the five important exponent properties and an example of each. You can think of them as the order of operations for exponents. Learn how to handle math problems with exponents here!

The Power of Zero: Simplifying Exponential Expressions

3. The Power of Zero: Simplifying Exponential Expressions

Raising a number to the power of zero is not the same as if the exponent is a number other than zero. This lesson will explain the rule involving using zero as an exponent and will give some examples of how it works.

Negative Exponents: Writing Powers of Fractions and Decimals

4. Negative Exponents: Writing Powers of Fractions and Decimals

Most numbers can be written in different ways, either as a fraction, decimal or exponent. This lesson will teach you how to write fractions and decimals using exponents and how to convert between the two.

Simplifying and Solving Exponential Expressions

5. Simplifying and Solving Exponential Expressions

What do we do with an exponent? In this lesson, we'll learn how to simplify and solve expressions containing exponents. We'll solve a variety of types of exponential expressions.

Rational Exponents

6. Rational Exponents

In this video, learn how to go from a rational exponent to a radical expression and back. No tricks or magic, just good math! We'll review the basics and look at a few examples.

Simplifying Expressions with Rational Exponents

7. Simplifying Expressions with Rational Exponents

Simplifying expressions with rational exponents is so easy. In fact, you already know how to do it! We simply use the exponent properties but with fractions as the exponent!
