Product Property of Radicals If you have the same index, then you can multiply the radicands.

Product Property of Radicals Also, go the other way, the simplify radical expressions

Simplify

Quotient Property of Radicals Quotients can be broken apart.

Some rules about Radicals Radicals can not have fractions in them. This is called Rationalizing the denominator.

Simplify

Multiply Radicals You can only multiply radicals if they have the same index.

Simplify

Conjugate You can not have radicals in the denominator. We have to use the conjugate to rational the denominator in fractions.
