In math, the square root of a number like 592 is a number that, when multiplied by itself, is equal to 592. We would show this in mathematical form with the square root symbol, which is called the radical symbol: √
Any number with the radical symbol next to it us called the radical term or the square root of 592 in radical form.
To explain the square root a little more, the square root of the number 592 is the quantity (which we call q) that when multiplied by itself is equal to 592:
So what is the square root of 592 and how do we calculate it? Well if you have a computer, or a calculator, you can easily calculate the square root. If you need to do it by hand, then it will require good old fashioned long division with a pencil and piece of paper.
For the purposes of this article, we'll calculate it for you (but later in the article we'll show you how to calculate it yourself with long division). The square root of 592 is 24.331050121193:
Is 592 a Perfect Square?
When the square root of a given number is a whole number, this is called a perfect square. Perfect squares are important for many mathematical functions and are used in everything from carpentry through to more advanced topics like physics and astronomy.
If we look at the number 592, we know that the square root is 24.331050121193, and since this is not a whole number, we also know that 592 is not a perfect square.
If you want to learn more about perfect square numbers we have a list of perfect squares which covers the first 1,000 perfect square numbers.
Is 592 a Rational or Irrational Number?
Another common question you might find when working with the roots of a number like 592 is whether the given number is rational or irrational. Rational numbers can be written as a fraction and irrational numbers can't.
The quickest way to check if a number is rational or irrational is to determine if it is a perfect square. If it is, then it's a rational number, but if it is not a perfect square then it is an irrational number.
We already know that 592 is not a rational number then, because we know it is not a perfect square.
Calculating the Square Root of 592
To calculate the square root of 592 using a calculator you would type the number 592 into the calculator and then press the √x key:
To calculate the square root of 592 in Excel, Numbers of Google Sheets, you can use the SQRT()
function:
Rounding the Square Root of 592
Sometimes when you work with the square root of 592 you might need to round the answer down to a specific number of decimal places:
10th: √592 = 24.3
100th: √592 = 24.33
1000th: √592 = 24.331
Finding the Square Root of 592 with Long Division
If you don't have a calculator or computer software available, you'll have to use good old fashioned long division to work out the square root of 592. This was how mathematicians would calculate it long before calculators and computers were invented.
Step 1
Set up 592 in pairs of two digits from right to left and attach one set of 00 because we want one decimal:
5

92

00

Step 2
Starting with the first set: the largest perfect square less than or equal to 5 is 4, and the square root of 4 is 2 . Therefore, put 2 on top and 4 at the bottom like this:
2  
5

92

00

4



Step 3
Calculate 5 minus 4 and put the difference below. Then move down the next set of numbers.
2  
5

92

4

92


Step 4
Double the number in green on top: 2 × 2 = 4. Then, use 4 and the bottom number to make this problem:
4? × ? ≤ 192
The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 4. Replace the question marks in the problem with 4 to get:
44 × 4 = 176
Now, enter 4 on top, and 176 at the bottom:
2  4  
5

92

00

4

Step 5
Calculate 192 minus 176 and put the difference below. Then move down the next set of numbers.
2  4  
5

92

Step 6
Double the number in green on top: 24 × 2 = 48. Then, use 48 and the bottom number to make this problem:
48? × ? ≤ 1600
The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 3.
Now, enter 3 on top:
2  4  3
