Question

Find the least number mus​

Answer 1

Answer:

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.
