11    Powers are entered by putting a <link xref="superscript">superscript number</link> after the value.
12    </p>

19    The inverse of a number can be entered using the inverse symbol ⁻¹ (<keyseq><key>Ctrl</key><key>I</key></keyseq>).
20    </p>
21    <example>
22    <p>
23    3⁻¹
24    </p>
25    </example>

27    Powers can also be calculated using the ^ symbol.
28    This allows the power to be an equation.

30    <example>
31    <p>
32    5^(6−2)
33    </p>

39    Square roots can be calculated using the  symbol (<keyseq><key>Ctrl</key><key>R</key></keyseq>).
40    </p>
41    <example>
42    <p>
43    √2
44    </p>
45    </example>
46    <p>
47    n-th roots can be calculated by putting a <link xref="superscript">subscript number</link> before the root sign.
