# 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}
