This document defines exponents and exponential form. It provides examples of writing numbers using exponential form, such as 4 * 4 * 4 = 43 and 9 * 9 * 9 * 9 = 94. It also gives examples of finding the value of numbers in exponential form, like 23 = 2 * 2 * 2 = 8. The document warns that 23 does not mean 2 * 3 = 6 and to be careful when evaluating exponential expressions.

Example: Writing Numbers in Exponential Form
4 • 4 • 4 = 43 9 • 9 • 9 • 9 = 94
Example: Finding the value of numbers in exponential form
23 = 2 • 2 • 2 = 8 (2 • 2=4 •2=8)
Warning: 23 does NOT mean 2 • 3=6 Be careful!
