-    <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>
