Answer:

A Perfect Square can end only in the numbers 0, 1, 4, 5, 6, or 9. If it doesn’t, the given number is not a Perfect Square. Now if it satisfies the above condition then check the digital summation of a number. In digital summation you keep on adding all the digits of a number till you get a single number.

A Perfect Square always have digital summation of one of these numbers ( 1, 4, 7, 9), if it doesn’t it’s not a Perfect Square.
