This is a program to calculate the n-th root of any number. This program uses the NEWTON_RAPTION_ITERATION method for calculation. The general formula to find the n-th root of any number is : *-------------------------------* * (((n-1)/n)*x0) + (1/n)*(N/d) * *-------------------------------* where n =1,2,3............ (n-th root). x0 is First approximate root. …
