# Ch 11: Exponents and Exponential Expressions

Master your understanding of exponents and exponential equations while getting ready for the mathematical reasoning portion of the General Educational Development (GED) exam. All of the lessons include a video and online self-assessment.

## Exponents and Exponential Equations - Chapter Summary

The purpose of this chapter is to teach you how to work with positive and negative exponents, which typically appear as small, raised numbers to the left of a figure. Each lesson covers a specific topic and includes an online quiz that can help you decide if you're ready to progress to the next tutorial. Designed to help you pass the mathematical reasoning section of the GED exam, the chapter covers the following:

• The use of exponents in mathematics
• Scientific notations, including definition, examples and use
• Simplifying and solving exponential expressions
• Order of operations
• Multiplying and dividing exponential expressions
• The power of zero in simplifying exponential expressions
• Negative exponents, including how to write powers of fractions and decimals
• The power of powers and simplifying exponential expressions

Viewing and interactive activities are based upon easy-to-understand graphics and practice problems that are similar to those you'll find on the GED. When you've finished the chapter, you should have an understanding of exponential rules and know how to apply them to different mathematical expressions.

### GED Mathematical Reasoning Objectives

The GED is a 4-part test that reflects the Common Core State Standards as they apply to high school students in grades 9-12. The mathematical reasoning section is composed of two parts and must be completed in 90 minutes. Over half of this section, or 55%, consists of questions related to algebraic problem solving. The remaining 45% will test your understanding of quantitative reasoning principles and procedures. To help you avoid any surprises on exam day, lesson objectives include:

• How exponents relate to multiplication
• Writing numbers using scientific notation
• Writing exponential notations for products
• Using the order of operations to simplify an exponential expression
• Multiplying and dividing exponential expressions
• Raising a real number to the 0 power to simplify an exponential expression
• Writing powers of fractions or decimals using negative exponents
• Raising a power to a power to simplify an exponential equation

Successful completion of the exam will demonstrate your understanding of mathematical concepts and procedures, including their academic and real-life applications. The second portion of the exam requires the use of an on-screen scientific calculator, which will be provided.
