Square Root of 7324

In this article we're going to calculate the square root of 7324 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 7324 (both with and without a computer/calculator).

Square Root of 7324 Definition

In mathematical form we can show the square root of 7324 using the radical sign, like this: √7324. This is usually referred to as the square root of 7324 in radical form.

So what is the square root? In this case, the square root of 7324 is the quantity (which we will call q) that when multiplied by itself, will equal 7324.

√7324 = q × q = q²

Is 7324 a Perfect Square?

In math, we refer to 7324 being a perfect square if the square root of 7324 is a whole number.

In this case, as we will see in the calculations below, we can see that 7324 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 7324 Rational or Irrational?

A common question is to ask whether the square root of 7324 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 7324 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 7324 is a perfect square so we also can see that √7324 is an irrational number.

Can the Square Root of 7324 Be Simplified?

7324 can be simplified only if you can make 7324 inside the radical symbol smaller. This is a process that is called simplifying the surd. In this example, the square root of 7324 can be simplified.

√7324 = 2√1831.

How to Calculate The Square Root of 7324 with a Calculator

If you have a calculator then the simplest way to calculate the square root of 7324 is to use that calculator. On most calculators you can do this by typing in 7324 and then pressing the √x key. You should get the following result:

√7324 ≈ 85.5804

How to Calculate the Square Root of 7324 with a Computer

On a computer you can also calculate the square root of 7324 using Excel, Numbers, or Google Sheets and the SQRT function, like so:

SQRT(7324) ≈ 85.580371581339

What is the Square Root of 7324 Rounded?

Sometimes you might need to round the square root of 7324 down to a certain number of decimal places. Here are the solutions to that, if needed.

10th: √7324 ≈ 85.6

100th: √7324 ≈ 85.58

1000th: √7324 ≈ 85.58

What is the Square Root of 7324 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 7324 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 7324 rounded to the nearest hundredth.

√7324

≈ 85.6/1

≈ 8558/100

≈ 85 29/50

What is the Square Root of 7324 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 7324:

√b = b^½

√7324 = 7324^½

How to Find the Square Root of 7324 Using Long Division

Finally, we can use the long division method to calculate the square root of 7324. 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 7324 in pairs of two digits from right to left and attach one set of 00 because we want one decimal:

73	24	00

---

Step 2

Starting with the first set: the largest perfect square less than or equal to 73 is 64, and the square root of 64 is 8 . Therefore, put 8 on top and 64 at the bottom like this:

8
73	24	00
64

---

Step 3

Calculate 73 minus 64 and put the difference below. Then move down the next set of numbers.

8
73	24	00
64
9	24

---

Step 4

Double the number in green on top: 8 × 2 = 16. Then, use 16 and the bottom number to make this problem:

16? × ? ≤ 924

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:

165 × 5 = 825

Now, enter 5 on top, and 825 at the bottom:

8	5
73	24	00
64
9	24
8	25

---

Step 5

Calculate 924 minus 825 and put the difference below. Then move down the next set of numbers.

8	5
73	24	00
64
9	24
8	25
0	99	00

---

Step 6

Double the number in green on top: 85 × 2 = 170. Then, use 170 and the bottom number to make this problem:

170? × ? ≤ 9900

The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 5.

Now, enter 5 on top:

8	5	5
73	24	00
64
9	24
8	25
0	99	00

---

That's it! The answer shown at the top in green. The square root of 7324 with one digit decimal accuracy is 85.6. 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.
