- 5.2: Simplifying Radical Expressions
- An algebraic expression that contains radicals is called a radical expression. We use the product and quotient rules to simplify them.

- 5.5: Rational Exponents
- In this section, we will define what rational (or fractional) exponents mean and how to work with them. All of the rules for exponents developed up to this point apply.

- 5.6: Solving Radical Equations
- A radical equation is any equation that contains one or more radicals with a variable in the radicand.

- 5.7: Complex Numbers and Their Operations
- There is no real number that when squared results in a negative number. We begin to resolve this issue by defining the imaginary unit, i , as the square root of −1 . In this way any square root of a negative real number can be written in terms of the imaginary unit. Such a number is often called an imaginary number.
