Answer:

1024 is the least perfect square with four digits

31^2 =961

32^2 =1024

33^2 =1089

34^2 =1156

Least number of four digits = 1000.

(32)2 is more than 1000 by 24.

So, the least number to be added to 1000 is 24.

1000 + 24 = 1024

Therefore, the smallest four digit number which is a perfect square is 1024.
