Simplifying Radical Expressions |
---|

A radical expression has been simplified when it meets the following conditions: -The index (n) is as small as possible. -The radicand contains no factors (except ‘1’) that are nth powers of an integer or polynomial. -The radicand contains no fractions. -No radicals appear in any denominator. |

Let's try to simply a radical expression:

We're almost finished. According to Step #4, we need to remove the radical from the denominator:

Now, we have a simplified answer that meets all four conditions.
