+ <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>
