Example 9: Simplify each of the following.

(a) To rationalize this denominator, the appropriate fraction with the value 1 is since that will eliminate the radical in the denominator, when used as follows:

Note we elected to find s principal root.

(b)

What can be multiplied with so the result will not involve a radical? The answer is That choice is made so that after they are multiplied, everything under the radical sign will be perfect cubes.

Conjugates

If a and b are unlike terms, then the conjugate of a + b is a – b, and the conjugate of a – b is a + b. The conjugate of Conjugates are used for rationalizing the denominator when the denominator is a two-termed expression involving a square root.

Example 10: Simplify

To rationalize the denominator of this expression, multiply by a fraction in the form of the denominator’s conjugate over itself.
