  • RootReduce[ expr ] attempts to reduce expr to a single Root object.
  • If expr consists only of integers and Root objects combined using algebraic operations, then the result from RootReduce[ expr ] will always be a single Root object.
  • Simple Root objects may in turn automatically evaluate to rational expressions or combinations of radicals.
  • See the Mathematica book: Section 3.4.3.
  • See also: FullSimplify, Solve, ToRadicals.
