Square Root 120 by Repeated Subtraction Method
The square root can be found by repeatedly subtracting odd numbers from the provided number until it equals zero. This process is known as repeated subtraction. So, In this process number of odd numbers we subtract here will be treated as a square root of 120.
- 120 – 1 = 119
- 119 – 3 = 116
- 116 – 5 = 111
- 111 – 7 = 104
- 104 – 9 = 95
- 95 – 11 = 84
- 84 – 13 = 71
- 71 – 15 = 56
- 56 – 17 = 39
- 39 – 19 = 20
- 20 – 21 = -1
So, here we have subtracted 11 odd numbers till now and past the zero and get the number in negative integer.
Therefore, The square root of 120 can be approximately near to 11.
