Expert Answer:

The square of a number ends up with any one of the digits 0, 1, 4, 5, 6, or 9.

Now, the number 187683 do not end up with any of these digits. So, it can obviously not be a perfect square.

However, the numbers 26544 and 3591025 ends up with 4 and 5 respectively. So, they can be perfect square numbers.
