I'll toss in my 2 cents and perhaps say something either stupid or obvious.
That is that if you have a number of say 1024 bits then you can compute the
cube root in 1024/3 operations where each operation in z^3. I do not know why
you need the number and I do not know if this is an acceptable c

Wrong question. BIGNUMs are for high precision *integer* arithmetic,
often in a finite ring (e.g. Z/pqZ). In this context cube roots either

Hopefully others will have better ideas but one possibility is to
use Newton's formula. I'm not sure what it is with cube roots but
it's probably something like:
