|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.
