# N-th number which is both a square and a cube

Given a number n, find the n-th number which is both a square and a cube. First few such numbers are 1, 64, 729, …

**Examples :**

Input : 3 Output :729 729 is square of 27 and cube of 3. Input :5 Output :15625

The idea is simple, n-th such number is n^{6}

## C++

`// CPP program to find n-th number which is both ` `// square and cube. ` `#include <bits/stdc++.h> ` `using` `namespace` `std; ` ` ` `int` `nthSquareCube(` `int` `n) ` `{ ` ` ` `return` `n*n*n*n*n*n; ` `} ` ` ` `// Driver code ` `int` `main() ` `{ ` ` ` `int` `n = 5; ` ` ` `cout << nthSquareCube(n); ` ` ` `return` `0; ` `} ` |
