Roots of
fractions or fractions with a root in the denominator are not simplified. To
eliminate roots in denominators, use the fact that 
and that any nonzero number over itself is
one. We will begin with square roots. If the denominator is a square root,
multiply the fraction by the denominator over itself. This will force the new
denominator to be a perfect square.
