Simplifying Radicals Calculator

This tool puts a radical in simplest form. It takes whole numbers only: one number under the root, an optional whole-number multiplier in front, and a root index from 2 to 10, so variables, fractions and full expressions are outside what it reads. The answer comes back as a multiplier and whatever is left under the root, written like 6 sqrt(2) or 3 root3(2), along with the square or nth-power factor that was removed and the decimal value. Negative numbers under the root are not accepted, since the result would be imaginary.
