 Math Central Quandaries & Queries
 Question from Annie, a student: How do I transform the equation 3 divided by 3 to it's fifth root to simple radical form (getting the radical out of the denominator)?

Hi Annie,

The numerator is and the denominator is .

Now you need to use one of the laws of exponents. They are

ab ac = ab + c
ab ac = ab - c as long as a ≠ 0, and
(ab)c = abc
