find the square root of 400 by long division methodfind the square ...

here is the answer.

Answer 2

Answer:

Step 1)

Set up 1156 in pairs of two digits from right to left:

11 56

Step 2)

Starting with the first set: the largest perfect square less than or equal to 11 is 9, and the square root of 9 is 3. Therefore, put 3 on top and 9 at the bottom like this:

3

11 56

9

Step 3)

Calculate 11 minus 9 and put the difference below. Then move down the next set of numbers.

3

11 56

9

2 56

Step 4)

Double the number in green on top: 3 × 2 = 6. Then, use 6 and the bottom number to make this problem:

6? × ? ≤ 256

The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 4. Replace the question marks in the problem with 4 to get:

64 × 4 = 256.

Now, enter 4 on top, and 256 at the bottom:

3 4

11 56

9

2 56

2 56

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 1156 is 34.
