...

tag.

The following is a valid HTML5 document using MathML:

XML/HTML CodeCopy content to clipboard

html   
<!doctype html>
  <html>
  <head>
  <meta charset="UTF-8">
  <title>Pythagorean theorem</title>
  </head>

        <mo>+</mo>
        <msup><mi>b</mi><mn>2</mn></msup>
        <mo>=</mo>
        <msup><mi>c</mi><mn>2</mn></msup>
      </mrow>
    </math>
  </body>
</html>
