Shouldn't the first example on that page be formatted a little better? and
use the numeric entity instead of the named one?

<math xmlns=3D"http://www.w3.org/1998/Math/MathML">

    <mrow>
      <msup>
        <mi>x</mi>

      <mrow>

At the end of this page, there&#39;s an example for the math expression<br>

Could someone tell me if the example is correct or not?<br>
