So what is the square root? In this case, the square root of 1069 is the quantity (which we will call q) that when multiplied by itself, will equal 1069.
√1069 = q × q = q2
Is 1069 a Perfect Square?
In math, we refer to 1069 being a perfect square if the square root of 1069 is a whole number.
In this case, as we will see in the calculations below, we can see that 1069 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 1069 Rational or Irrational?
A common question is to ask whether the square root of 1069 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 1069 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 1069 is a perfect square so we also can see that √1069 is an irrational number.
Can the Square Root of 1069 Be Simplified?
1069 can be simplified only if you can make 1069 inside the radical symbol smaller. This is a process that is called simplifying the surd. In this example square root of 1069 cannot be simplified.
√1069 is already in its simplest radical form.
How to Calculate The Square Root of 1069 with a Calculator
If you have a calculator then the simplest way to calculate the square root of 1069 is to use that calculator. On most calculators you can do this by typing in 1069 and then pressing the √x key. You should get the following result:
√1069 ≈ 32.6956
How to Calculate the Square Root of 1069 with a Computer
On a computer you can also calculate the square root of 1069 using Excel, Numbers, or Google Sheets and the SQRT function, like so:
SQRT(1069) ≈ 32.695565448544
What is the Square Root of 1069 Rounded?
Sometimes you might need to round the square root of 1069 down to a certain number of decimal places. Here are the solutions to that, if needed.
10th: √1069 ≈ 32.7
100th: √1069 ≈ 32.7
1000th: √1069 ≈ 32.696
What is the Square Root of 1069 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 1069 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 1069 rounded to the nearest hundredth.
√1069
≈ 32.7/1
≈ 3270/100
≈ 32 3.5/5
What is the Square Root of 1069 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 1069:
√b = b½
√1069 = 1069½
How to Find the Square Root of 1069 Using Long Division
Finally, we can use the long division method to calculate the square root of 1069. 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 1069 in pairs of two digits from right to left and attach one set of 00 because we want one decimal:
|
10
|
69
|
00
|
Step 2
Starting with the first set: the largest perfect square less than or equal to 10 is 9, and the square root of 9 is 3 . Therefore, put 3 on top and 9 at the bottom like this:
| 3 | ||
|
10
|
69
|
00
|
|
9
|
Step 3
Calculate 10 minus 9 and put the difference below. Then move down the next set of numbers.
| 3 | ||
|
10
|
69
|
00
|
|
9
|

|
1
|
69
|
Step 4
Double the number in green on top: 3 × 2 = 6. Then, use 6 and the bottom number to make this problem:
6? × ? ≤ 169
The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 2. Replace the question marks in the problem with 2 to get:
62 × 2 = 124
Now, enter 2 on top, and 124 at the bottom:
| 3 | 2 | |
|
10
|
69
|
00
|
|
9
|

|

|
69

|
Step 5
Calculate 169 minus 124 and put the difference below. Then move down the next set of numbers.
| 3 | 2 | |
|
10
|
69
|

Step 6
Double the number in green on top: 32 × 2 = 64. Then, use 64 and the bottom number to make this problem:
64? × ? ≤ 4500
The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 6.
Now, enter 6 on top:
| 3 | 2 | 6 |
|
10
|
69

That's it! The answer shown at the top in green. The square root of 1069 with one digit decimal accuracy is 32.7. 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.
