**Square root of 48 definition**

The square root of 48 in mathematical form is written with the radical sign like this √48. We call this the square root of 48 in radical form. The square root of 48 is a quantity (q) that when multiplied by itself will equal 48.

√48 = q × q = q

^{2}

**Is 48 a perfect square?**

48 is a perfect square if the square root of 48 equals a whole number. As we have calculated further down on this page, the square root of 48 is not a whole number.

48 is not a perfect square.

**Is the square root of 48 rational or irrational?**

The square root of 48 is a rational number if 48 is a perfect square. It is an irrational number if it is not a perfect square. Since 48 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 48?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.

√48 is an irrational number

**Can the square root of 48 be simplified?**

You can simplify 48 if you can make 48 inside the radical smaller. We call this process "to simplify a surd". The square root of 48 can be simplified.

√48 = 4√3

**How to calculate the square root of 48 with a calculator**

The easiest and most boring way to calculate the square root of 48 is to use your calculator! Simply type in 48 followed by √x to get the answer. We did that with our calculator and got the following answer with 9 decimal numbers:

√48 ≈ 6.928203230

**How to calculate the square root of 48 with a computer**

If you are using a computer that has Excel or Numbers, then you can enter SQRT(48) in a cell to get the square root of 48. Below is the result we got with 13 decimals. We call this the square root of 48 in decimal form.

SQRT(48) ≈ 6.9282032302755

**What is the square root of 48 rounded?**

The square root of 48 rounded to the nearest tenth, means that you want one digit after the decimal point. The square root of 48 rounded to the nearest hundredth, means that you want two digits after the decimal point. The square root of 48 rounded to the nearest thousandth, means that you want three digits after the decimal point.

10th: √48 ≈ 6.9

100th: √48 ≈ 6.93

1000th: √48 ≈ 6.928

**What is the square root of 48 as a fraction?**

Like we said above, since the square root of 48 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 48 rounded to the nearest hundredth.

√48

≈ 6.93/1

≈ 693/100

**≈ 6 93/100**

**What is the square root of 48 written with an exponent?**

All square roots can be converted to a number (base) with a fractional exponent. The square root of 48 is no exception. Here is the rule and the answer to "the square root of 48 converted to a base with an exponent?":

√b = b

^{½}

√48 = 48

^{½}

**How to find the square root of 48 by long division method**

Here we will show you how to calculate the square root of 48 using the long division method with one decimal place accuracy. This is the lost art of how they calculated the square root of 48 by hand before modern technology was invented.

**Step 1)**

Set up 48 in pairs of two digits from right to left and attach one set of 00 because we want one decimal:

48 | 00 |

**Step 2)**

Starting with the first set: the largest perfect square less than or equal to 48 is 36, and the square root of 36 is 6. Therefore, put 6 on top and 36 at the bottom like this:

6 | ||||

48 | 00 | |||

36 | ||||

**Step 3)**

Calculate 48 minus 36 and put the difference below. Then move down the next set of numbers.

6 | ||||

48 | 00 | |||

36 | ||||

12 | 00 | |||

**Step 4)**

Double the number in green on top: 6 × 2 = 12. Then, use 12 and the bottom number to make this problem:

12? × ? ≤ 1200

The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 9. Now, enter 9 on top:

6 | 9 | |||

48 | 00 | |||

36 | ||||

12 | 00 | |||

That's it! The answer is on top. The square root of 48 with one digit decimal accuracy is 6.9.
