# 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 n6
