About the square root sign. Historical information about a math tutor. Root as indicated in the computer

A number of users who actively work with mathematics, statistics and other exact sciences may need to type the root symbol √ on the keyboard. At the same time, there is no image of such a symbol on any of the keyboard buttons, and the user wonders: how to do this? In this material I will help such users, I will tell you how to write a root on the keyboard, I will explain what methods exist for this, and how to indicate the root of 3,4,5 degrees on the keyboard.

Writing the root on the computer

How to put the square root sign on the keyboard

Many users, when deciding how to write a root on a PC keyboard, use the surrogate symbol “^” located on the 6 key at the top of the keyboard (activated by switching to the English layout, pressing the Shift key and the “6” button at the top).

Some users also use the letter combination sqrt (square root), cbrt (cube root), and so on.

At the same time, although these are fast, they are not sufficient techniques. To set the root sign normally, do the following:

If you don’t know how to enter a dog from the keyboard, then you definitely need to read the detailed instructions for entering it, since when typing E-mail you cannot do without the dog sign.

How to write a root on the keyboard using a symbol table

An alternative to this option is to use a special symbol table available in the Windows OS.

1. Click on "Start", then select "All Programs";
2. Then “Standard”, then “Service”, where select “Character table”.
3. There, find the root sign √, click on it, click on the “Select” button, then “Copy” and copy it into the text you need using the Ctrl + V keys.

The Word text editor (as well as Excel) also has a corresponding symbol table that can be used for our tasks. You can find it by going to the “Insert” tab and clicking on “Symbol” on the right, and then clicking on “Other symbols” just below, this will help you in solving the issue of writing a root in Word.

You can also use the “Formula” option in the “Insert” tab according to the algorithm described in this video.

How to write the 3rd, 4th, 5th root on the keyboard

At the same time, the question may also arise about how to write the square root on the keyboard and others like them.

For example, the root of 3,4,5 degrees on the keyboard can be written like this:

3√X (instead of the number 3 you can use the corresponding designation from the symbol table (³)

At the same time, despite the fact that the system has an image of the cube root ∛ and the fourth root ∜, it will not be possible to type them using Alt and the number keys. This is only possible using HTML decimal codes (∛ and ∜) and Unicode hex codes (∛ and ∜). For me, it is better to use the forms of notation that I described just above.

Conclusion

In this material, I described different options for how to write a root on the keyboard of your computer. The most impatient can use the ^ sign, but it would be more accurate and correct to use the key combination Alt+251 and put the root sign as it is designated in accordance with the generally accepted symbol standard.

Method No. 1. Use Alt key and number pad

To use this method, make sure that your keyboard has a number pad (on the right or combined with letters) and that the NumLock indicator is lit. If it is not lit, turn it on using the NumLock/NumLk key.

On laptops or compact keyboards, you may also need to hold down the Fn key; you can learn more about this from the instructions for your laptop. So, to type the root sign on the keyboard, you need to hold down the Alt key and sequentially enter the numbers 2, 5 and 1 on the number pad, and then release the pressed key.

If you did everything correctly, a radical sign will appear on the screen. This is the easiest way to write a root on the keyboard. But what if you need the cube or fourth root?

Method No. 2. If your keyboard doesn't have a number pad

If it so happens that your keyboard does not have a number pad and there is no way to write the root on the keyboard using the first method - do not despair! You can also use any search engine and, by entering the “root sign” into it, you will get a symbol that can already be copied into your article.

If you do not have the Internet, then you can use the standard Windows application - the symbol table. It's very easy to find. To do this, go to the "Start" menu, find the "Accessories" folder in it, and in it - the "System" folder. You can also press the Win+R key combination and enter charmap.exe in the field that opens and press Enter. This method applies not only to the root symbol, but also to others.

Method number 3. Use decimal code (HTML code)

This method also does not require entering numbers from the number pad. To add a square, cube or fourth root to your article in this way, you need to type these sequences of symbols and numbers on your keyboard:

• √ - for square root;
• ∛ - for cube root

Method No. 4. Use hexadecimal code (Unicode)

This method is used extremely rarely due to its impracticality, but it would be an omission not to mention it. Who knows when it will come in handy. If the site where your article will be located uses Unicode (although UTF-8 has long been widely used), you can use these sequences:

• √ - for square root;
• ∛ - for cube root;
• ∜ - for a root of the fourth degree.

As you can see, there is nothing complicated in the question of how to find the square root on the keyboard. Now you know four ways to write it, as well as the cubic or fourth root.

Sometimes working with Microsoft Word documents goes beyond normal typing, fortunately, the program’s capabilities allow this. We have already written about creating tables, graphs, charts, adding graphic objects, and the like. We also talked about inserting symbols and mathematical formulas. In this article we will look at a related topic, namely, how to put a square root in Word, that is, the usual root sign.

Inserting a root sign follows the same pattern as inserting any mathematical formula or equation. However, a couple of nuances are still present, so this topic deserves detailed consideration.

1. In the document in which you need to put the root, go to the tab "Insert" and click in the place where this sign should be.

2. Click on the button "An object" located in the group "Text".

3. In the window that appears in front of you, select “Microsoft Equation 3.0”.

4. The mathematical formula editor will open in the program window, and the appearance of the program will completely change.

5. In the window "Formula" click on the button “Fraction and Radical Patterns”.

6. From the drop-down menu, select the root sign you want to add. The first is the square root, the second is any other higher degree (instead of the “x” sign you can enter the degree).

7. After adding the root sign, enter the required numeric value under it.

8. Close the window "Formula" and click on an empty area of ​​the document to switch to normal operation mode.

The root sign with a digit or number underneath it will be in a field similar to a text field or object field "WordArt", which can be moved around the document and resized. To do this, just pull one of the markers framing this field.

To exit the mode of working with objects, simply click in an empty area of ​​the document.

Advice: To return to the mode of working with the object and reopen the window "Formula", double-click with the left mouse button in the field in which the object you added is located
