- ToRadicals can always give expressions in terms of radicals when the highest degree of the polynomial that appears in any Root object is four.
- There are some cases in which expressions involving radicals can in principle be given, but ToRadicals cannot find them.
- If Root objects in expr contain parameters, ToRadicals[expr] may yield a result that is not equal to expr for all values of the parameters.
- ToRadicals automatically threads over lists, as well as equations, inequalities, and logic functions.
