# Ch 5: High School Algebra: Exponents and Exponential Expressions

Watch video lessons and learn how to write, simplify and solve exponential expressions. These easy-to-follow lessons are just a portion of our online study guide and video collection.

## Exponents and Exponential Expressions - Chapter Summary and Learning Objectives

Exponents are abbreviated notations that are used to indicate how many times a number or mathematical expression can be multiplied by itself. In a mathematical operation, they usually appear as a raised superscript to the right of a number and are referred to as powers. In this chapter, your instructor will show you how these shorthand notations can be used to write very large and small numbers that are too cumbersome or awkward to present in decimal form. You'll also learn the rules for simplifying and solving exponential expressions.

Each video in the series is devoted to a specific topic, such as the order of operations or the power of zero, and builds upon what you learned in the previous lesson. When you've finished the chapter and taken the online quizzes, you should be ready to:

• Write exponential notations
• Use the order of operations to solve exponential expressions
• Use the power of zero rule to solve exponential expressions
• Multiply and divide exponential expressions
• Use the power of powers rule to solve exponential expressions
• Use negative exponents to indicate powers of decimals or fractions
