Answer 2

When we calculate square root of 6412, the remainder is 12

It represenetcs that the square of 80 is less than 6412

The next number is 81 and (81)2 = 6561

So, the number to be added to 6412 = 6561 - 6412 = 149

Hence the required perfect square number is 6561

Now √(6561) = √(81 * 81) = 81
