Chapter 6: Exponents and Exponential Functions
Introduction
Here you'll learn all about exponents in algebra. You will learn the properties of exponents and how to simplify exponential expressions. You will learn how exponents can help you write very large or very small numbers with scientific notation. You will also learn how to solve different types of exponential equations where the variable appears as the exponent or the base. Finally, you will explore different types of exponential functions of the form

Summary
You learned that in an expression like

am×an=am+n 
aman=am−n (if m>n,a≠0) 
(am)n=amn 
(ab)n=anbn 
(ab)n=anbn (b≠0) 
a0=1 (a≠0) 
a−m=1am 
amn=am−−−√n=(a√n)m
You learned that scientific notation is a way to express large or small numbers in the form
You learned that to solve exponential equations with variables in the exponent you should try to rewrite the equations so the bases are the same. Then, set the exponents equal to each other and solve. If the equation has a variable in the base you can try to get rid of the exponent or, make the exponents on each side of the equation the same and then set the bases equal to each other and solve.
Finally, you learned all about exponential functions. You learned that for exponential functions of the form
