Answer 2

Answer:

3 Or 7

The square root of 1156 is 34.

at once place the digit 9.

we know that 3 square equals to 9 and 7 square equals to 49 , so 3 at the end will give 9 at once place and 7 at the end will give also 9 at ones place.

therefore in the square root of 2209, at once place, the number will be either 3 or 7
