Answer 2

Step-by-step explanation:

Given number = 6412

Finding the nearest root is 80

80^{2} = 640080

2

=6400 which is less than 6412

We take the next number 81^{2} = 656181

2

=6561

Therefore, 6561 - 6412 = 1496561−6412=149

Therefore, the required number = 149

6412 + 149 = 65616412+149=6561 which is a perfect square

The perfect square is the number which is obtained on multiplying the same number two times.
