How Do You Solve Radicals with Two Radicals

Isolate the radical on one side of the equation.Square both sides of the equation.Solve the new equation.Check the answer. Some solutions obtained may not work in the original equation.

What happens when you square both sides?

Both sides are equal, so squaring both sides keeps both sides equal, because you are performing the same operation to the same values. Well we know the two sides are equal, hence the equals sign. If you multiply something by itself that is what squaring is.

Can you cube root both sides?

When an equation has a cube root, we follow the same process of using inverse operations. When you come across the cube root, all you need to do is cube each side to get rid of it. … In the equation below, you can see that we got rid of the cube root first by raising both sides to the power of 3.
