Find the greatest number with 3 digits which is a perfect square. also find the square root of number obtained |
|
Answer» We know that the largest 3 digit number is 999. So we will FIND out the square root of 999 by LONG division method and check whether it is a perfect square or not. 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 4 digit number. Therefore to find the largest 3 digit perfect square we will SUBTRACT 38 from 999. 999 - 38 = 961. Hence 961 is the largest 3 digit perfect square whose square root is 31. Hope it helped ! |
