Question
There turns out to be several generalizations; one of them we will call S(n, m), which asks if there are integer solutions of the form: a n 1 + a n 2 + · · · + a n m = c n . Fermat’s last theorem is just S(n, 2). Show that the generalization of the theorem is in fact not true in general! By this, show that S(n, 4) for n 5 is false, by implementing a C++ program that will find a counterexample; i.e., some positive integers a1, · · · , a4, c and n 5 such that a n 1 + · · · + a n 4 = c n . You can be guaranteed that all of a1, · · · , a4, c 1000, so you don’t have to verify infinitely many possible cases.

Explanation / Answer
#include <bits/stdc++.h>
using namespace std;
void testSomeNumbers(int limit, int n)
{
if (n < 3)
return;
for (int a=1; a<=limit; a++)
for (int b=a; b<=limit; b++)
{
// Check if there exists a triplet
int pow_sum = pow(a, n) + pow(b, n);
double c = pow(pow_sum, 1.0/n);
int c_pow = pow((int)c, n);
if (c_pow == pow_sum)
{
cout << "Count example found";
return;
}
}
cout << "No counter example within given"
" range and data";
}
// driver code
int main()
{
testSomeNumbers(10, 3);
return 0;
}
