| ### Function Root ( elt-ids^fra/ord^num I, elt-ord^rat r ) -> elt-ids^fra/ord^num ### Description An rth root of I if such exists. ### Examples x_E := FiniteField(29); x_F := FunctionField(x_E); x_E_eckig_t := PolynomialAlgebra(x_E); x_F_eckig_x := PolynomialAlgebra(x_F); x_G := FunctionField((x_F_eckig_x.1)^3 + (x_F.1)^2); x_o := MaximalOrderFinite(x_G); x_B := Basis(x_o); x_a := (x_B[2])^(-7)*x_o; Root(x_a, 7);
