My Mathematica notebook

   nthRoots.nb

may help you. You can download it from the Files page at my web site:

   http://www.math.umass.edu/~murray/Math_421_Eisenberg/

For its graphics, that notebook relies upon David Park's "Presentations" 
Mathematica application. In case that's not available to you, on that 
same Files page I have a pdf version of the evaluated notebook.
