推荐答案
对MathML的浏览器支持仍然相当杂乱无章，但是您可以通过将MathJax库添加到Web文档中，使其在几乎所有浏览器中都能正常工作.只需将以下两行添加到您的HTML中:
Browser support for MathML is still rather patchy, but you can get it working in just about any browser by adding the MathJax library to your web document. Just add the following two lines to your HTML:
<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>
<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script>
然后应正确呈现.尝试运行以下代码段，例如:
It should then render correctly. Try running the following snippet for example:
<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>
<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script>
<p> <math xmlns="http://www.w3.org/1998/Math/MathML"><mrow><msup><mfenced><mrow><mi>a</mi><mo>+</mo><mi>b</mi></mrow></mfenced><mn>2</mn></msup><mo>=</mo><msup><mi>a</mi><mn>2</mn></msup><mo>+</mo><msup><mi>b</mi><mn>2</mn></msup><mo>+</mo><mn>2</mn><mi>a</mi><mi>b</mi></mrow></math></p>
