Square Root of 29
In this article we're going to calculate the square root of 29 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 29 (both with and without a computer/calculator).
Square Root of 29 Definition
In mathematical form we can show the square root of 29 using the radical sign, like this: √29. This is usually referred to as the square root of 29 in radical form.
So what is the square root? In this case, the square root of 29 is the quantity (which we will call q) that when multiplied by itself, will equal 29.
√29 = q × q = q2
Is 29 a Perfect Square?
In math, we refer to 29 being a perfect square if the square root of 29 is a whole number.
In this case, as we will see in the calculations below, we can see that 29 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 29 Rational or Irrational?
A common question is to ask whether the square root of 29 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 29 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 29 is a perfect square so we also can see that √29 is an irrational number.
Can the Square Root of 29 Be Simplified?
29 can be simplified only if you can make 29 inside the radical symbol smaller. This is a process that is called simplifying the surd. In this example square root of 29 cannot be simplified.
√29 is already in its simplest radical form.
How to Calculate The Square Root of 29 with a Calculator
If you have a calculator then the simplest way to calculate the square root of 29 is to use that calculator. On most calculators you can do this by typing in 29 and then pressing the √x key. You should get the following result:
√29 ≈ 5.3852
How to Calculate the Square Root of 29 with a Computer
On a computer you can also calculate the square root of 29 using Excel, Numbers, or Google Sheets and the SQRT function, like so:
SQRT(29) ≈ 5.385164807135
What is the Square Root of 29 Rounded?
Sometimes you might need to round the square root of 29 down to a certain number of decimal places. Here are the solutions to that, if needed.
10th: √29 ≈ 5.4
100th: √29 ≈ 5.39
1000th: √29 ≈ 5.385
What is the Square Root of 29 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 29 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 29 rounded to the nearest hundredth.
≈ 5 39/100
What is the Square Root of 29 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 29:
√b = b½
√29 = 29½
How to Find the Square Root of 29 Using Long Division
Finally, we can use the long division method to calculate the square root of 29. 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.
Set up 29 in pairs of two digits from right to left and attach one set of 00 because we want one decimal:
Starting with the first set: the largest perfect square less than or equal to 29 is 25, and the square root of 25 is 5 . Therefore, put 5 on top and 25 at the bottom like this:
Calculate 29 minus 25 and put the difference below. Then move down the next set of numbers.
Double the number in green on top: 5 × 2 = 10. Then, use 10 and the bottom number to make this problem:
10? × ? ≤ 400
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:
That's it! The answer shown at the top in green. The square root of 29 with one digit decimal accuracy is 5.4. 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.
