10th: √8731 ≈ 93.4
100th: √8731 ≈ 93.44
1000th: √8731 ≈ 93.440
What is the square root of 8731 as a fraction?
Like we said above, since the square root of 8731 is an irrational number, we cannot make it into an exact fraction. However, we can make it into an approximate fraction using the square root of 8731 rounded to the nearest hundredth.
√8731
≈ 93.44/1
≈ 9344/100
≈ 93 11/25
What is the square root of 8731 written with an exponent?
All square roots can be converted to a number (base) with a fractional exponent. The square root of 8731 is no exception. Here is the rule and the answer to "the square root of 8731 converted to a base with an exponent?":
√b = b½
√8731 = 8731½
How to find the square root of 8731 by long division method
Here we will show you how to calculate the square root of 8731 using the long division method with one decimal place accuracy. This is the lost art of how they calculated the square root of 8731 by hand before modern technology was invented.
Step 1)
Set up 8731 in pairs of two digits from right to left and attach one set of 00 because we want one decimal:
| 87 | 31 | 00 |
Step 2)
Starting with the first set: the largest perfect square less than or equal to 87 is 81, and the square root of 81 is 9. Therefore, put 9 on top and 81 at the bottom like this:
| 9 | |||
| 87 | 31 | 00 | |
| 81 | |||
Step 3)
Calculate 87 minus 81 and put the difference below. Then move down the next set of numbers.
| 9 | |||
| 87 | 31 | 00 | |
| 81 | |||
| 6 | 31 | ||
Step 4)
Double the number in green on top: 9 × 2 = 18. Then, use 18 and the bottom number to make this problem:
18? × ? ≤ 631
The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 3. Replace the question marks in the problem with 3 to get:
183 × 3 = 549.
Now, enter 3 on top, and 549 at the bottom:
| 9 | 3 | ||
| 87 | 31 | 00 | |
| 81 | |||
| 6 | 31 | ||
| 5 | 49 | ||
Step 5)
Calculate 631 minus 549 and put the difference below. Then move down the next set of numbers.
| 9 | 3 | ||
| 87 | 31 | 00 | |
| 81 | |||
| 6 | 31 | ||
| 5 | 49 | ||
| 0 | 82 | 00 | |
Step 6)
Double the number in green on top: 93 × 2 = 186. Then, use 186 and the bottom number to make this problem:
186? × ? ≤ 8200
The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 4. Now, enter 4 on top:
| 9 | 3 | 4 | |
| 87 | 31 | 00 | |
| 81 | |||
| 6 | 31 | ||
| 5 | 49 | ||
| 0 | 82 | 00 | |
That's it! The answer is on top. The square root of 8731 with one digit decimal accuracy is 93.4. Did you notice that the last two steps repeat the previous two steps. You can add decimals by simply adding more sets of 00 and repeating the last two steps over and over.
