So what is the square root? In this case, the square root of 5055 is the quantity (which we will call q) that when multiplied by itself, will equal 5055.
√5055 = q × q = q2
Is 5055 a Perfect Square?
In math, we refer to 5055 being a perfect square if the square root of 5055 is a whole number.
In this case, as we will see in the calculations below, we can see that 5055 is not a perfect square.
To find out more about perfect squares, you can read about them and look at a list of 1000 of them in our What is a Perfect Square? article.
Is The Square Root of 5055 Rational or Irrational?
A common question is to ask whether the square root of 5055 is rational or irrational. Rational numbers can be written as a fraction and irrational numbers cannot.
A quick way to check this is to see if 5055 is a perfect square. If it is, then it is a rational number. If it's not a perfect square then it's an irrational number.
We already know if 5055 is a perfect square so we also can see that √5055 is an irrational number.
Can the Square Root of 5055 Be Simplified?
5055 can be simplified only if you can make 5055 inside the radical symbol smaller. This is a process that is called simplifying the surd. In this example square root of 5055 cannot be simplified.
√5055 is already in its simplest radical form.
How to Calculate The Square Root of 5055 with a Calculator
If you have a calculator then the simplest way to calculate the square root of 5055 is to use that calculator. On most calculators you can do this by typing in 5055 and then pressing the √x key. You should get the following result:
√5055 ≈ 71.0985
How to Calculate the Square Root of 5055 with a Computer
On a computer you can also calculate the square root of 5055 using Excel, Numbers, or Google Sheets and the SQRT function, like so:
SQRT(5055) ≈ 71.098523191414
What is the Square Root of 5055 Rounded?
Sometimes you might need to round the square root of 5055 down to a certain number of decimal places. Here are the solutions to that, if needed.
10th: √5055 ≈ 71.1
100th: √5055 ≈ 71.1
1000th: √5055 ≈ 71.099
What is the Square Root of 5055 as a Fraction?
We covered earlier in this article that only a rational number can be written as a fraction, and irrational numbers cannot.
Like we said above, since the square root of 5055 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 5055 rounded to the nearest hundredth.
√5055
≈ 71.1/1
≈ 7110/100
≈ 71 4.9999999999995/50
What is the Square Root of 5055 Written with an Exponent?
All square root calculations can be converted to a number (called the base) with a fractional exponent. Let's see how to do that with the square root of 5055:
√b = b½
√5055 = 5055½
How to Find the Square Root of 5055 Using Long Division
Finally, we can use the long division method to calculate the square root of 5055. This is very useful for long division test problems and was how mathematicians would calculate the square root of a number before calculators and computers were invented.
Step 1
Set up 5055 in pairs of two digits from right to left and attach one set of 00 because we want one decimal:
|
50
|
55
|
00
|
Step 2
Starting with the first set: the largest perfect square less than or equal to 50 is 49, and the square root of 49 is 7 . Therefore, put 7 on top and 49 at the bottom like this:
| 7 | ||
|
50
|
55
|
00
|
|
49
|
Step 3
Calculate 50 minus 49 and put the difference below. Then move down the next set of numbers.
| 7 | ||
|
50
|
55
|
00
|
|
49
|
||
|
1
|
55
|
Step 4
Double the number in green on top: 7 × 2 = 14. Then, use 14 and the bottom number to make this problem:
14? × ? ≤ 155
The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 1. Replace the question marks in the problem with 1 to get:
141 × 1 = 141
Now, enter 1 on top, and 141 at the bottom:
| 7 | 1 | |
|
50
|
55
|
00
|
|
49
|
||
|
1
|
55
|
|
|

|
41
|
Step 5
Calculate 155 minus 141 and put the difference below. Then move down the next set of numbers.
| 7 | 1 | |
|
50
|
55
|
00
|
|

|
0
|
14
|
00
|
Step 6
Double the number in green on top: 71 × 2 = 142. Then, use 142 and the bottom number to make this problem:
142? × ? ≤ 1400
The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 0.
Now, enter 0 on top:
| 7 | 1 | 0 |
|
50
|
55
|
00
|
|

That's it! The answer shown at the top in green. The square root of 5055 with one digit decimal accuracy is 71.1. Notice that the last two steps actually repeat the previous two. To add decimal places to your answe you can simply add more sets of 00 and repeat the last two steps.
