I doubt that the AKS primality test is of any practical relevance, although it's a _great_ theoretical achievement.

So if you plan to add a _n_-th root to `BigDecimal` in a followup PR, then please keep going on this one.
Otherwise, I can't see a strong need for a `BigInteger` _n_-th root in the platform, although I might be wrong.
