Hello Friend, 

Its ur answer.

Every square of a number ends with the digit 0, 1, 4, 5, 6, 9.i.e. A number might be a square if the digit at unit place is either 0, 1, 4, 5, 6 or 9.


In 2826, the unit place digit is 6. So it would be a square number.  

By prime factorisation,
2826 = 2 X 2 X 3 X 157
= 2√3X157
=2√471.


Therefore, it is not a perfect square.
