Nth root of a number.rb

# Given two numbers x and n, calculate the nth root of x.

# This means that being r = result, r^n = x; Examples

# root(4, 2)    # 2 (the square root of 4 is 2 , 2^2 = 4);
# root(8, 3)    # 2 (the cube root of 8 is 2   , 2^3 = 8);
# root(256, 4)  # 4 (the 4th root of 256 is 4  , 4^4 = 256);
# root(9, 2)    # 3 (the square root of 9 is 3 , 3^2 = 9)
