  <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>
