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 n6

## C++

 `// C++ program to find n-th number which is both``// square and cube.``#include ``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;``}`

## Java

 `// Java program to find n-th number``// which is both square and cube.``class` `GFG {``    ` `    ``static` `int` `nthSquareCube(``int` `n)``    ``{``        ``return` `n * n * n * n * n * n;``    ``}``    ` `    ``// Driver code``    ``public` `static` `void` `main(String[] args)``    ``{``        ``int` `n = ``5``;``        ` `        ``System.out.println(nthSquareCube(n));``    ``}``}` `// This code is contributed by``// Smitha Dinesh Semwal`

## Python3

 `# program to find n-th number``# which is both square and cube.` `def` `nthSquareCube(n):` `    ``return` `n ``*` `n ``*` `n ``*` `n ``*` `n ``*` `n`  `# Driver code``n ``=` `5``print``(nthSquareCube(n))``# This code is contributed by``# Smitha Dinesh Semwal`

## C#

 `// C# program to find n-th number``// which is both square and cube.``using` `System;` `class` `GFG``{``    ` `    ``static` `int` `nthSquareCube(``int` `n)``    ``{``        ``return` `n * n * n * n * n * n;``    ``}``    ` `    ``// Driver code``    ``static` `public` `void` `Main ()``    ``{``        ``int` `n = 5;``        ` `        ``Console.WriteLine(nthSquareCube(n));``    ``}``}` `// This code is contributed by Ajit.`
