Answer 2

Step-by-step explanation:

when we try to find out square root of 1400 using long division method

3 | 1400 | 3

+3 | -9. |

-------------

6 | 500 |

now we will think of such number as when put beside 6 and multiplied with that number , the result is just greater. than 500

now

67*7 = 469, 68*8 = 544

so we will take 8

in that case the remainder will be -44. ( so to say only, remainder cannot be negative)

now the number would be perfect square if remainder would be zero.

to make -44 equal to zero we need to add 44 to it.

so our answer is 44.

this will make the number 1444 which will be square of 38
