Hmm, I am somewhat reluctant to introduce a "\cdot" there. Putting
parenthesis around 6^(1/3) in LaTeX-output would either bloat the printing
routines or bloat the normal output with superfluous parenthesis as well,
as in 2(x^2) instead of 2 x^2. May I suggest to change the space to a
hard space "\ " in LaTeX? This would then produce
2\ 6^{{(\frac{1}{3})}}
which seems legible to me, when typeset. (Try it with a two-digit
basis.) Would that be okay for you folks?

PS: It's a real pity LaTeX is dedicated to printed format instead of
semantical format. :-(
