T66​

Answer 1

Answer:

Here we can see that 999 is not a perfect square as it leaves 38 as remainder. So if 38 will be added to 999 then it will become a 4digit number. Therefore to find the largest 3 digit perfect square we will subtract 38 from 999. Hence 961 isthe largest 3 digit perfect square whose square root is 31.
