In this lesson we are going to solve some radical equations. A radical equation is an equation in which variables are present in the radical. To solve a radical equation, isolate the radical and raise each side of the equation to an appropriate power. For example, for dealing with square roots we will square both sides. If we have the 4th root, then we will raise both sides to the 4th power. With these ones it is extremely important that you check your solutions when you are done. In this lesson, you'll also learn how to deal with problems when there is more than one radical expression in the equation.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
