How do you simplify radicals?

To simplify a radical expression, simplify any perfect squares or cubes, fractional exponents, or negative exponents, and combine any like terms that result. If there are fractions in the expression, split them into the square root of the numerator and square root of the denominator.

How do you multiply radicals with radicals?

To multiply two radicals together, you can first rewrite the problem as one radical. The two numbers inside the square roots can be multiplied together under one square root. Simplify what's inside the radical to write your final answer.

How do you subtract radicals?

Subtraction of radicals follows the same set of rules and approaches as addition—the radicands and the indices (plural of index) must be the same for two (or more) radicals to be subtracted. In the three examples that follow, subtraction has been rewritten as addition of the opposite.
