Answer 2

The smallest four-digit number is 1000 but square root of 1000 gives the value 31.62 which 1000 is not a perfect square. In order to obtain the smallest 4-digit perfect square, numbers higher than 1000 must be checked. The possibility is the square of 32 as the square of 31 will be less than 1000.

Required smallest 4-digit perfect square = 32 * 32 = 1024
