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> </page>
