Question

Square root of 3136 in division method​

Answer 1

Answer:

Look at the first pair of digits and find the nearest square lower than 31: answer is 25=5^2. Subtract 25 from 31 to leave 6, and bring down the next pair of digits. ... so the next digit in the answer is 6 and when we subtract 636 from 636 we get zero, so the square root of 3136=56.
