2. Step-by-step explanation:

   31 ² = 961

   32 ² = 1024

   33² = 1089

   34³ = 1156

   LEAST number of four digit = 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 4 digit number which is a perfect square is 1024

   hope it helps you
