Answer» (3) 31Step-by-step explanation:Firstly , the square root of 1234321 = 1111Secondly , the square of 51 = 2601Now the SUBTRACTION ,2601 - 1111 = 14901490 is not a perfect square .The square root of 1490 is 38.6So , LET's take square of 39 , which is 1521.So , 1521 - 1490 = 31 Therefore , 31 is the smallest number which should be ADDED to the resultant to make it a perfect square.
