When dividing radical expressions, we use the quotient rule. This lesson will describe the quotient rule and how to use it to solve these radical expressions. The quotient rule can be used to simplify square roots of quotients. This lesson will define the quotient rule and show you how it is used to simplify square roots. Radical expressions containing denominators are not simplified completely unless the denominator is free of radical symbols.
This lesson will teach you how to remove a radical from the denominator of a fraction through a process called rationalizing the denominator. There are specific rules governing adding and subtracting radical expressions.
This lesson will describe these rules and give examples of how they are used. Multiplying radical expressions with more than two terms can be confusing. This lesson will take some of the confusion away by giving clear steps for multiplying these expressions. It will also provide some examples to help solidify the steps.
Solving radical equations is not any more difficult than solving other algebraic equations. This lesson will show you how to solve equations containing a square root and give some real-world examples. Solving equations with two radical terms takes some patience and care, but it really is not difficult. This lesson will show you the steps to solve these more complicated equations plus give you some examples to follow.

Help with Radicals in Geometry In math, a radical is the root of a number. Examples of radicals include (square root of 4), which equals 2 because 2 x 2 = 4, and (cube root of 8), which also equals 2 .
For example, radical seven is equal to a decimal, so it is an imperfect square. Radical eight, radical 15 and radical 23 are all imperfect squares as well. Simplifying Perfect Squares. If a radical is a perfect .
