<title>Powers and Roots</title>
<p>
Powers are entered by putting a <link xref="superscript">superscript number</link> after the value.
</p>
<example>
<p>
5²
</p>
</example>
<p>
The inverse of a number can be entered using the inverse symbol ⁻¹ (<keyseq><key>Ctrl</key><key>I</key></keyseq>).
</p>
<example>
<p>
3⁻¹
</p>
</example>
<p>
Powers can also be calculated using the ^ symbol.
This allows the power to be an equation.
</p>
<example>
<p>
5^(6−2)
</p>
</example>
<p>
If your keyboard does not have a <key>^</key> key you can use <key>*</key> twice.
</p>
<p>
Square roots can be calculated using the symbol (<keyseq><key>Ctrl</key><key>R</key></keyseq>).
</p>
<example>
<p>
√2
</p>
</example>
<p>
n-th roots can be calculated by putting a <link xref="superscript">subscript number</link> before the root sign.
</p>
<example>
<p>
₃√2
</p>
</example>
