Question

find the least number which must be added to each of the following number so as to get perfect square.

Answer 1

what are the numbers??
let's take an example :-
Q-525
it is not a perfect square
but it varies in between this:-
22^2 --- 525--- 23^2
now to get the least number we have to do
23^2 - 525
= 529 - 525
= 4 (ans)
so when we add 4 to 525
we will get a perfect square.
