Explanation:

Forming pairs: 01 and 22Find a number Y (1) such that whose square is Bring down the next pair 22, to the right of the remainder 0. The new dividend is now 22.Add the last digit of the quotient (1) to the divisor (1) i.e. 1 + 1 = 2. To the right of 2, find a digit Z (which is 1) such that 2Z × Z Divide 22 by 21 with the quotient as 1, giving the remainder = 22 - 21 × 1 = 22 - 21 = 1.Now, let's find the decimal places after the quotient 11.Bring down 00 to the right of this remainder 1. The new dividend is now 100.Add the last digit of quotient to divisor i.e. 1 + 21 = 22. To the right of 22, find a digit Z (which is 0) such that 22Z × Z Divide 100 by 220 with the quotient as 0, giving the remainder = 100 - 220 × 0 = 100 - 0 = 100.Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 122.

Therefore, the square root of 122 by long division method is 11.0 approximately.
