Superscript values are not announced properly by most screen readers.
However I have tried using the unicode values of <sup> i.e. &sup;. Using
this NVDA is properly announcing the values for &sup2; and &sup3; but not
beyond them.
<span>150&sup2;</span><br />
I am not sure how the values visually appear when the unicode values are
used.
