My MPL.Math sublibrary, available in the Vault under
the Template Metaprogramming directory, contains
implementations of the power<> and integral_power<>
metafunctions that you seek.

I might consider a generalized root<> metafunction if
I can get significant compile-time savings over the
naive implementation.  MPL.Math already has a
square_root<> metafunction.
