**Find the smallest integer n such that √(n + 99) – √n < 1.
**

√(n + 99) – √n < 1

n + 99 < 1 + n + 2√n

98 < 2√n

49 < √n

Hence, the smallest integer = 49² + 1 = 2402 .

Why are we adding 1 to 2401?

Hi Surbhi.

49 < √nThis means that n^2>49^2

The smallest integer greater than 49^2 is arrived at by adding 1 to 49^2.

That’s why we add 1 to 2401.
