Looking to include an advanced equation with a radix or simply the square root sign ( √ ) in a Word document? Find out here **how to insert the square root sign as part of a mathematical formula or as a Unicode character with Word** (Windows, Mac, mobile and online).

## First, Cash Paying Dividends

In medieval Europe’s cities, drinking cups were popularly made of silver.

Since just about all money was also made of silver in the form of coins, those cups were money that paid dividends daily in the form of sheer utility.

Now, want to write about getting the radius of such a coin (or a cylindrical cup perhaps) with $r=\sqrt{\frac{V}{\pi h}}$? Let’s use that square root symbol:

### Word for Windows and Word for Mac

Time needed: 2 minutes

To use the square root (or radix) sign as part of an equation or expression in Microsoft Word for Windows as well as for Mac:

over*Type equation here*.**Parens**: Don’t let the display of the opening parenthesis throw you; the parens will take the arguments for the radix.**Now type the degree for the radix followed by**`&`

followed by what is to appear underneath the radix symbol followed by the closing parenthesis`)`

.**Square root**: For a square root, leave the place before`&`

empty.**Square root example**: Type`\sqrt(&a+2)`

for the square root of*a**+ 2*, for example.**Cube root example**: Type`\sqrt(3&a+b)`

for the cube root of*a + b.***Press**`Space`.**Make it inline**: By default, Word will insert equations as a separate, centered block; see below for making the equation appear inline.

### How can I use a square root in LaTeX?

Using the amsmath package, you can insert a square root in LaTeX with `\sqrt{}`

.

To insert a square root symbol and other radices in LaTeX:

- Use
`\sqrt[degree]{radicand}`

.

#### Example

```
\usepackage{amsmath}
…
$\sqrt[3]{a+2}$
```

will result in

.

Using additional commands, you can change the position of the index and the height of the radix symbol.
