I am not sure what you want to say here: 'nthRoot is in
AlgebraicNumber which under right conditions models
algebraic numbers and in Expression, where we have
things more general than numbers.
OK, to give a specific example, what's the relationship
between sqrt(2) (a 'nthRoot) and %x0 (a 'rootOf):
(1) -> sqrt(2)
+-+
(1) \|2
(2) -> rootsOf(x^2-2)
(2) [%x0, - %x0]
