Question

find the greatest three digit number which is perfect square

Answer 1

to find greatest three digit number


999 is a largest three digit number but it's not a perfect square it leaves the remainder 38


so I am assuming


if we subtract 999 from 38


so

999 -38

= 961



so as we factor 961


31 *31 which is 31


square root of 961 = √961


hence answer is = 31


so 961 is the greatest three digit number
