Timeline for In MathJax, how can I get the index of a cube root of a tall expression to be at the right level?

Normally the $3$ of a cube root is in sub/superscript size, but \displaystyle gives its normal in-line size. Exactly like the difference between \frac and \dfrac when typesetting fractions in-line. I'm fairly sure that extra 'd' stands for 'display'. It should be possible to specify a different font size (if one is available), but that becomes kludgier. Don't know how to lower/raise the surd, and that may have other side effects. I would not worry about it too much here. When producing a document I might dig deeper, or ask at Tex.SE- there are very competent people there :-)
