Square Root of 17

Here we will define, analyze, simplify, and calculate the square root of 17. We start off with the definition and then answer some common questions about the square root of 17. Then, we will show you different ways of calculating the square root of 17 with and without a computer or calculator. We have a lot of information to share, so let's get started!



Square root of 17 definition
The square root of 17 in mathematical form is written with the radical sign like this √17. We call this the square root of 17 in radical form. The square root of 17 is a quantity (q) that when multiplied by itself will equal 17.

17 = q × q = q2



Is 17 a perfect square?
17 is a perfect square if the square root of 17 equals a whole number. As we have calculated further down on this page, the square root of 17 is not a whole number.

17 is not a perfect square.



Is the square root of 17 rational or irrational?
The square root of 17 is a rational number if 17 is a perfect square. It is an irrational number if it is not a perfect square. Since 17 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 17?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.

17 is an irrational number



Can the square root of 17 be simplified?
You can simplify 17 if you can make 17 inside the radical smaller. We call this process "to simplify a surd". The square root of 17 cannot be simplified.

17 is already in its simplest radical form.



How to calculate the square root of 17 with a calculator
The easiest and most boring way to calculate the square root of 17 is to use your calculator! Simply type in 17 followed by √x to get the answer. We did that with our calculator and got the following answer with 9 decimal numbers:

17 ≈ 4.123105626




How to calculate the square root of 17 with a computer
If you are using a computer that has Excel or Numbers, then you can enter SQRT(17) in a cell to get the square root of 17. Below is the result we got with 13 decimals. We call this the square root of 17 in decimal form.

SQRT(17) ≈ 4.1231056256177



What is the square root of 17 rounded?
The square root of 17 rounded to the nearest tenth, means that you want one digit after the decimal point. The square root of 17 rounded to the nearest hundredth, means that you want two digits after the decimal point. The square root of 17 rounded to the nearest thousandth, means that you want three digits after the decimal point.

10th: √17 ≈ 4.1

100th: √17 ≈ 4.12

1000th: √17 ≈ 4.123



What is the square root of 17 as a fraction?
Like we said above, since the square root of 17 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 17 rounded to the nearest hundredth.

17
≈ 4.12/1
≈ 412/100
≈ 4 3/25



What is the square root of 17 written with an exponent?
All square roots can be converted to a number (base) with a fractional exponent. The square root of 17 is no exception. Here is the rule and the answer to "the square root of 17 converted to a base with an exponent?":

b = b½

17 = 17½



How to find the square root of 17 by long division method
Here we will show you how to calculate the square root of 17 using the long division method with one decimal place accuracy. This is the lost art of how they calculated the square root of 17 by hand before modern technology was invented.

Step 1)
Set up 17 in pairs of two digits from right to left and attach one set of 00 because we want one decimal:

1700



Step 2)
Starting with the first set: the largest perfect square less than or equal to 17 is 16, and the square root of 16 is 4. Therefore, put 4 on top and 16 at the bottom like this:

4
1700
16



Step 3)
Calculate 17 minus 16 and put the difference below. Then move down the next set of numbers.

4
1700
16
100



Step 4)
Double the number in green on top: 4 × 2 = 8. Then, use 8 and the bottom number to make this problem:

8? × ? ≤ 100

The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 1. Now, enter 1 on top:

41
1700
16
100

That's it! The answer is on top. The square root of 17 with one digit decimal accuracy is 4.1.
