Answer 2

Answer:

1024, √1024 = 32

Step-by-step explanation:

Smallest 4-digit number = 1000.

Finding Square root by long division:

       31

     --------

3  | 1000

   | 9

      --------

61 |   100

        61

        -------

           39

Here,

Remainder = 39

Since Remainder is not 0,

So, 1000 is not a perfect square.

From the above method,

we observe that (31) ² < 1000 < 32²

The required number to be added = 32² - 1000

= 1024 - 1000

= 24

So, the least number to be added is 24.

Required perfect square number = 1000 + 24 = 1024.

And, √1024 = 32

Therefore, The least 4 - digit perfect square number = 1024.

Hope it helps!
