उत्तर

The square root of 1750 can be calculated by long division method as follows:

  41
4 `bar17  bar50`
-16
81     150
     -81
        69

The remainder is 69.

Clearly, 412 = 1681 < 1750

422 = 1764 > 1750.

Hence, the number to be added is 1764 − 1750 = 14, and the square root of 1764 is 42.
