Square Root of 5723

In this article we're going to calculate the square root of 5723 and explore what the square root is and answer some of the common questions you might. We'll also look at the different methods for calculating the square root of 5723 (both with and without a computer/calculator).

Square Root of 5723 Definition

In mathematical form we can show the square root of 5723 using the radical sign, like this: √5723. This is usually referred to as the square root of 5723 in radical form.

So what is the square root? In this case, the square root of 5723 is the quantity (which we will call q) that when multiplied by itself, will equal 5723.

√5723 = q × q = q²

Is 5723 a Perfect Square?

In math, we refer to 5723 being a perfect square if the square root of 5723 is a whole number.

In this case, as we will see in the calculations below, we can see that 5723 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 5723 Rational or Irrational?

A common question is to ask whether the square root of 5723 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 5723 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 5723 is a perfect square so we also can see that √5723 is an irrational number.

Can the Square Root of 5723 Be Simplified?

5723 can be simplified only if you can make 5723 inside the radical symbol smaller. This is a process that is called simplifying the surd. In this example square root of 5723 cannot be simplified.

√5723 is already in its simplest radical form.

How to Calculate The Square Root of 5723 with a Calculator

If you have a calculator then the simplest way to calculate the square root of 5723 is to use that calculator. On most calculators you can do this by typing in 5723 and then pressing the √x key. You should get the following result:

√5723 ≈ 75.6505

How to Calculate the Square Root of 5723 with a Computer

On a computer you can also calculate the square root of 5723 using Excel, Numbers, or Google Sheets and the SQRT function, like so:

SQRT(5723) ≈ 75.650512225629

What is the Square Root of 5723 Rounded?

Sometimes you might need to round the square root of 5723 down to a certain number of decimal places. Here are the solutions to that, if needed.

10th: √5723 ≈ 75.7

100th: √5723 ≈ 75.65

1000th: √5723 ≈ 75.651

What is the Square Root of 5723 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 5723 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 5723 rounded to the nearest hundredth.

√5723

≈ 75.7/1

≈ 7565/100

≈ 75 6.5000000000001/10

What is the Square Root of 5723 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 5723:

√b = b^½

√5723 = 5723^½

How to Find the Square Root of 5723 Using Long Division

Finally, we can use the long division method to calculate the square root of 5723. 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 5723 in pairs of two digits from right to left and attach one set of 00 because we want one decimal:

57	23	00

---

Step 2

Starting with the first set: the largest perfect square less than or equal to 57 is 49, and the square root of 49 is 7 . Therefore, put 7 on top and 49 at the bottom like this:

7
57	23	00
49

---

Step 3

Calculate 57 minus 49 and put the difference below. Then move down the next set of numbers.

7
57	23	00
49
8	23

---

Step 4

Double the number in green on top: 7 × 2 = 14. Then, use 14 and the bottom number to make this problem:

14? × ? ≤ 823

The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 5. Replace the question marks in the problem with 5 to get:

145 × 5 = 725

Now, enter 5 on top, and 725 at the bottom:

7	5
57	23	00
49
8	23
7	25

---

Step 5

Calculate 823 minus 725 and put the difference below. Then move down the next set of numbers.

7	5
57	23	00
49
8	23
7	25
0	98	00

---

Step 6

Double the number in green on top: 75 × 2 = 150. Then, use 150 and the bottom number to make this problem:

150? × ? ≤ 9800

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:

7	5	6
57	23	00
49
8	23
7	25
0	98	00

---

That's it! The answer shown at the top in green. The square root of 5723 with one digit decimal accuracy is 75.7. 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.
