6.2 Multiplying and Dividing Radical Expressions

You can only use this property if the radicals are real numbers and if the indexes are the same.

Ex) Can you use the property for multiplying radicals?

Simplest radical form means that the radicand contains no perfect nth powers among its factors, there are no fraction radicands and there are no radicals in the denominator of a fraction. Answers must ALWAYS be in simplest radical form.

Ex) Simplify

You can only use this property if the radicals are real numbers and if the indexes are the same and if the radicand in the denominator is not equal to zero.

Ex) Simplify.

Ex) Simplify.

To eliminate a radical in the denominator, you must RATIONALIZE. Ex) Simplify.

Ex) Simplify.
