How to find the square root of 7569 by long division method
Here we will show you how to calculate the square root of 7569 using the long division method. This is the lost art of how they calculated the square root of 7569 by hand before modern technology was invented.

Step 1)
Set up 7569 in pairs of two digits from right to left:

Step 2)
Starting with the first set: the largest perfect square less than or equal to 75 is 64, and the square root of 64 is 8. Therefore, put 8 on top and 64 at the bottom like this:

8
75	69
64

Step 3)
Calculate 75 minus 64 and put the difference below. Then move down the next set of numbers.

8
75	69
64
11	69

Step 4)
Double the number in green on top: 8 × 2 = 16. Then, use 16 and the bottom number to make this problem:

16? × ? ≤ 1169

The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 7. Replace the question marks in the problem with 7 to get:

167 × 7 = 1169.

Now, enter 7 on top, and 1169 at the bottom:

8	7
75	69
64
11	69
11	69

The difference between the bottom two numbers is zero, therefore, you are done! The answer is the green numbers on top. Once again, the square root of 7569 is 87.
