'''Integer roots'''
 
The task is to write a program that computes an approximation to the principal N<sup>th</sup> root of X as the largest integer less than or equal to R for which R^<sup>N</sup>=X. N is a positive integer. X is a non-negative integer. The root R is a non-negative real number.
 
Example: With N=3 and X=8 you would calculate the number 2 because <math>2^3=8</math>.
