You want to write **numbers with powers** (example: 10 to the power of 6 = 10^{6} ) on your keyboard, in Word or in another word processing software ? To do so, it will depend on the power used:

## 1. To make the symbol "squared" (ex: 10 squared: 10²)

To write "squared", you can press the **key located just below the Esc key** (the key at the top left of your keyboard), otherwise you can also press the `Alt`key (to the left of your Space bar) + "**253**", then release the `Alt` key.

+`Alt`**+**(Alt`2``5``3`**253) -> 10 to the power of 2 = 10²**

## 2. To make the symbol "cubed" (example: 2 cubic meters: 2m³)

To write "cube", you can press the " **Alt** " key (to the left of your Space bar) + " **252** ", then release the "Alt" key.

`Alt`**+**Alt`2``5``2`**"252) -> 10 to the power of 3 = 10³**

## 3. To make the powers or exponents greater than 3 (example: **10 to the power of 4** or **10 to the power of 5** : **10 **^{4} or **10 **^{5} )

^{4}

^{5}

Above the power "3", there is no keyboard shortcut available, it will depend on where you want to write your power or your exponent:

- In
**Microsoft**tools**(Word, Powerpoint, Outlook, etc.):**The easiest way is to**select the figure**to be superseded then to use the following**keyboard shortcut**:`Ctrl``Shift ⇧``=`**+ =**" to the left of the Return key)**.**- Example:
**10 to the power of 8:**- We write
**108**, we**select 8**and we do the**combination**`Ctrl``Shift ⇧``=`**→ 10**^{8}

- We write

- Example:

- In
**OpenOffice**: Same method but with a different combination: Select the number to put in superscript or in power then perform the key combination :`Ctrl``Shift ⇧``P`

**IMPORTANT** : Note that you can **also use this method to write letters by superscribing** as for the **abbreviations of first** : **1 ^{st }**or

**second : 2**. This technique works will all letters or symbols.

^{nd }Conversely, if you want to put the number or letters at the bottom, as for typical chemical formulas: **H _{2}O, **you just have to type:
