How to find the square root of 36 by long division method
Here we will show you how to calculate the square root of 36 using the long division method. This is the lost art of how they calculated the square root of 36 by hand before modern technology was invented.
Step 1)
Set up 36 in pairs of two digits from right to left:
| 36 |
Step 2)
Starting with the first set: the largest perfect square less than or equal to 36 is 36, and the square root of 36 is 6. Therefore, put 6 on top and 36 at the bottom like this:
| 6 | ||||
| 36 | ||||
| 36 | ||||
The difference between the bottom two numbers is zero, therefore, you are done! The answer is the green number on top. Once again, the square root of 36 is 6.
