Someone will probably give you a better answer. But, for now, here are the
dots one level higher:
\starttext
\permanent\protected\def\pow#1#2{\mathord{#1}^{#2}}
\im{\pow{\pow{\pow{\pow{\sqrt2}{\sqrt2}}{\sqrt2}}{\sqrt2}}{{}^{\udots}}=2}
\stoptext
I don't immediately know how to make them continue to shrink (in any
reasonable way, anyway).
