Ch 22: TExES Core Subjects 4-8: Powers & Exponential Expressions

About This Chapter

This chapter's videos and quizzes are designed to refresh your knowledge of powers and exponential expressions. These kinds of equations will appear on the Texas Examinations of Educator Standards (TExES) Core Subjects 4-8 test.

TExES Core Subjects 4-8: Powers & Exponential Expressions - Chapter Summary

The video lessons in this chapter are intended for Texas teachers who will soon be taking their TExES Core Subjects 4-8 test. They will prep the student for answering test questions related to:

  • The five exponent properties
  • Zero and negative exponents and rational exponents
  • Simplification of expressions with exponents
  • Scientific notation
  • The order of operations
  • Multiplying and dividing exponential expressions
  • The power of zero and the power of powers

Lessons are short videos, averaging 5-10 minutes, and each is accompanied by a quiz for checking your comprehension. There is also a feature for contacting an expert with any questions that you may have about powers and exponential expressions.

What Are the Five Main Exponent Properties?

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!

How to Define a Zero and Negative Exponent

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!

How to Simplify Expressions with Exponents

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!

Rational Exponents

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.

Scientific Notation: Definition and Examples

5. Scientific Notation: Definition and Examples

Scientific notation is a special way of writing numbers so they are easier to work with. This lesson will define scientific notations and show some examples of how to convert numbers from standard notation to scientific notation and back.

Exponential Expressions & The Order of Operations

6. 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.

Multiplying Exponential Expressions

7. Multiplying Exponential Expressions

There are certain rules that govern working with exponential expressions. This lesson deals with the rule for multiplying exponential expressions. It will describe the rule and give some examples of how it works.

Dividing Exponential Expressions

8. Dividing Exponential Expressions

Any time you work with expressions that contain exponents, you have to follow a specific set of rules that are not the same as when you are working with expressions that do not contain exponents. This lesson will describe the rules associated with dividing terms that contain exponents.

The Power of Zero: Simplifying Exponential Expressions

9. 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.

Power of Powers: Simplifying Exponential Expressions

10. Power of Powers: Simplifying Exponential Expressions

Mathematics is a very logical science. There is a rule for everything and not many exceptions to those rules. Working with exponents is no different. This lesson will describe the rule for raising a power to a power and also will give some examples in how to solve them.
