# How to insert square root symbol or radical sign in Word

**square root**symbol

**√**(also known as a

**,**

*radical sign***,**

*radical symbol***,**

*root symbol***, or**

*radix***) is often used in various documents. Microsoft Word offers convenient functionality for beautifully styling formulas.**

*surd*However, in some texts, the **root** symbol is used as part of an equation and a standalone mark. Less commonly, documents use the **Cube root ∛** and the **Fourth root ∜** symbols, which also are easy to insert into a Word document.

** Do not use a square root symbol to indicate a checkmark!** See
how to insert a check mark symbol in a document.

## I. Using the Equation:

Equations are excellent if you do not need to care about the format and compatibility with previous versions of Microsoft Office (a recommended approach for physical science and mathematics that require a lot of math expressions in the text with consistent fonts for all equations and symbols):

** 1. ** In the paragraph where you want to insert the
** root** symbol, click

**Alt+=**to insert the equitation block:

** 2. ** In the equitation block, without any additional
efforts, you can enter some mathematical symbols by typing
** \+Name of the symbol**:

## II. Using AutoCorrect for Math:

When you work with many documents and ** often** need to paste a single special
symbol, you may not want to insert an equation each time. Microsoft Word offers a
helpful feature named

**AutoCorrect**. The

**AutoCorrect**options in Microsoft Word propose two different ways to quickly add any special character, such as a

**symbol or**

*square root***, or even large pieces of text:**

*radical sign*- Using
the
**Replace text as you type**function of the**AutoCorrect**options. - Using the
**Math AutoCorrect**options:

Using this method, you can benefit from the **Math AutoCorrect** options without inserting an equation. To turn on or turn off the **AutoCorrect** of the **Math** symbols, do the following:

** 1. ** On the **File** tab, click **Options**:

** 2. ** In the **Word Options** dialog box, on the
**Proofing** tab, click the **AutoCorrect Options...** button:

** 3. ** In the **AutoCorrect** dialog box, on the **Math AutoCorrect** tab, select the **Use Math AutoCorrect rules outside of the math regions** option:

After clicking **OK**, you can use any of the listed ** Names of symbols**, and Microsoft Word will replace them with the appropriate characters:

** Note**: If you do not need the last replacement, click

**Ctrl+Z**to cancel it.

## III. Using a shortcut key:

Microsoft Word offers a pre-defined shortcut key for popular symbols such as ** square root**.

- Type
**221a**or**221A**(does not matter, uppercase or lowercase), immediately after that press**Alt+X**to insert thesymbol:*square root***√** - Type
**221b**or**221B**, and press**Alt+X**to insert thesymbol:*cube root***∛** - Type
**221c**or**221C**, and press**Alt+X**to insert thesymbol:*fourth root***∜**

** Note**: You can see the combination in the

**Character code**field in the

**Symbol**dialog box (see below).

## IV. Using a Symbol dialog box (the most common but not the most comfortable way):

To open the **Symbol** dialog box, on the **Insert** tab, in the **Symbols** group, select the **Symbol** button, and then click **More Symbols...**:

On the **Symbol** dialog box:

- To insert the
from the current font (if the font provides the square root glyph), from the*Square Root***Subset**dropdown list, select the**Mathematical Operators**: - To insert the
from the*Square Root***Symbol**font, from the**Font**dropdown list, choose the**Symbol**font:

** Note**: To insert a

**symbol from the**

*square root***Symbol**font (a better-looking glyph), you can create a shortcut key (see how to create a shortcut key).
