How to calculate the square root of 7015 with a computer
If you are using a computer that has Excel or Numbers, then you can enter SQRT(7015) in a cell to get the square root of 7015. Below is the result we got with 13 decimals. We call this the square root of 7015 in decimal form.
SQRT(7015) ≈ 83.7555968279135
What is the square root of 7015 rounded?
The square root of 7015 rounded to the nearest tenth, means that you want one digit after the decimal point. The square root of 7015 rounded to the nearest hundredth, means that you want two digits after the decimal point. The square root of 7015 rounded to the nearest thousandth, means that you want three digits after the decimal point.
10th: √7015 ≈ 83.8
100th: √7015 ≈ 83.76
1000th: √7015 ≈ 83.756
What is the square root of 7015 as a fraction?
Like we said above, since the square root of 7015 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 7015 rounded to the nearest hundredth.
√7015
≈ 83.76/1
≈ 8376/100
≈ 83 19/25
What is the square root of 7015 written with an exponent?
All square roots can be converted to a number (base) with a fractional exponent. The square root of 7015 is no exception. Here is the rule and the answer to "the square root of 7015 converted to a base with an exponent?":
√b = b½
√7015 = 7015½
How to find the square root of 7015 by long division method
Here we will show you how to calculate the square root of 7015 using the long division method with one decimal place accuracy. This is the lost art of how they calculated the square root of 7015 by hand before modern technology was invented.
Step 1)
Set up 7015 in pairs of two digits from right to left and attach one set of 00 because we want one decimal:
| 70 | 15 | 00 |
Step 2)
Starting with the first set: the largest perfect square less than or equal to 70 is 64, and the square root of 64 is 8. Therefore, put 8 on top and 64 at the bottom like this:
| 8 | |||
| 70 | 15 | 00 | |
| 64 | |||
Step 3)
Calculate 70 minus 64 and put the difference below. Then move down the next set of numbers.
| 8 | |||
| 70 | 15 | 00 | |
| 64 | |||
| 6 | 15 | ||
Step 4)
Double the number in green on top: 8 × 2 = 16. Then, use 16 and the bottom number to make this problem:
16? × ? ≤ 615
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:
163 × 3 = 489.
Now, enter 3 on top, and 489 at the bottom:
| 8 | 3 | ||
| 70 | 15 | 00 | |
| 64 | |||
| 6 | 15 | ||
| 4 | 89 | ||
Step 5)
Calculate 615 minus 489 and put the difference below. Then move down the next set of numbers.
| 8 | 3 | ||
| 70 | 15 | 00 | |
| 64 | |||
| 6 | 15 | ||
| 4 | 89 | ||
| 1 | 26 | 00 | |
Step 6)
Double the number in green on top: 83 × 2 = 166. Then, use 166 and the bottom number to make this problem:
166? × ? ≤ 12600
The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 7. Now, enter 7 on top:
| 8 | 3 | 7 | |
| 70 | 15 | 00 | |
| 64 | |||
| 6 | 15 | ||
| 4 | 89 | ||
| 1 | 26 | 00 | |
That's it! The answer is on top. The square root of 7015 with one digit decimal accuracy is 83.7. 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.
