How can we find perfect square?
You can also tell if a number is a perfect square by finding its square roots. Finding the square root is the inverse (opposite) of squaring a number. If you find the square root of a number and it’s a whole integer, that tells you that the number is a perfect square. For instance, the square root of 25 is 5.

What are the last digits of perfect squares?
Proving properties about the last digits of perfect squares. We all know that all perfect squares always end in 1, 4, 5, 6, 9, or an even number of zeroes. And we have also noticed that for a number that ends in 1, 4, 9 its tens digit will always be even ( 2, 4, 6, 8, 0 ).
Is the tens digit of a perfect square always even?
Thus, a is even. If a perfect square is even, then it is divisible by 4. Thus, if it ends in 0, 4, or 8 (the latter is not possible) the tens digit is even. If it ends in 2 or 6 (the former is not possible) then the tens digit is odd.
What are the limitations of perfect squares?
– If a number ends with 2, 3, 7 or 8 then it can’t be perfect square. -Square of any natural number has last two digits same as that of last two digits of squares of first twenty–five natural numbers.
Can a square end with 8?
The last digit of the square of a number that ends with 8, ends with what 8�8 or 64 ends with, namely 4. The last digit of the square of a number that ends with 9, ends with what 9�9 or 81 ends with, namely 1. So squares can only end with 0,1,4,5,6, and 9 Therefore squares cannot end with 2,3,7, or 8.
