Fastest way How to check if a number is a Perfect Square or not

Digital roots are 1, 4, 7 or 9. ...

If unit digit ends in 5, ten's digit is always 2.

If it ends in 6, ten's digit is always odd (1, 3, 5, 7, and 9) otherwise it is always even. ...

If a number is divisible by 4, its square leaves a remainder 0 when divided by 8.
