| We cannot simplify the fraction because the numerator and
denominator have no common factors except 1 and -1.
Instead we will write the radical as a quotient of two radicals. Then we
will try to simplify each radical so that we can write the expression
without a radical in the denominator. |
 |
| Use the Division Property of Radicals
to write the radical as a quotient of
two radicals.
|
 |
| For each radical, factor the radicand.
Use perfect fourth power factors
when possible. |
 |
| Write as a product of radicals.
Place each perfect fourth power
under its own radical symbol. |
 |
| Simplify the fourth root of each
perfect fourth power.
|
 |
| Multiply the factors outside
the radical. |
 |
| So, |
