- Defining zero and negative exponents
- Simplifying expressions with exponents and rational exponents

With the help from our exponent-based lessons, you will be better prepared to work toward a high score on the PSAT math test. These lessons allow you to focus on key elements by watching bite-sized, easy-to-understand videos. We also offer supplementary quizzes that test your knowledge regarding exponents. After you complete these quizzes, you're given immediate feedback on the concepts you excel at and the concepts you'll likely need to spend more time studying.

### PSAT Math Objectives

The PSAT math test has 48 questions across two sections (calculator and non-calculator) that must be completed within 70 minutes. The following three areas are emphasized on the PSAT math test:

- Heart of Algebra
- Problem solving and data analysis
- Passport to Advanced Math

Cosponsored by the National Merit Scholarship Corporation (NMSC), the PSAT aims to help you become familiar with the SAT format, and it allows you to gauge your preparedness to take the SAT. Your PSAT scores are used to identify trouble areas that need to be strengthened. By taking the PSAT, you are granted the opportunity to use the NMSC's tools for college and career planning. The NMSC may select you to participate in their scholarship programs depending on your PSAT scores.

### 1. 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!

### 2. How to Define a Zero and Negative Exponent

The zero and negative exponent properties are two you will use quite a lot in mathematics. The negative exponent property can be confusing, but when you remember a couple fun ideas, you will get it right every time!

### 3. How to Simplify Expressions with Exponents

In this video, we will put all of the exponent properties we have learned together. Don't let lots of numbers and letters confuse you! Simplifying exponents can be easy and fun!

### 4. 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.

### 5. 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!
