Consider the no. 3944484
Note that (1987)^2=3948169
This is greater than 3944484
So consider a number 1987−1=1986
(1986)^2=3944196
Thus it implies that,
3944196<3944484<3948169
So the least perfect square which is lesser
than 3944484 is 3944196
Therefore the number to be subtracted from 3944484 to make it perfect square is,
3944484−3944196=288
The square root of the perfect square so
obtained is 1986.
