Answer 1

since,8100 is square of 90
so,
5 is the least number that must be subtracted from 8105 to make it a perfect square.

Answer 2

Answer:

i.e.         8105

             -     5

           ______

              8100

Now,

$\sqrt[2]{8100}$ = 90

Hence, 8100 has now become a perfect square (As its square root is giving us a whole number)
