 Perhaps Mr Rachida would like to reproduce some formulas in this page: Trigonometric constants expressed in real radicals. Answer

 The result from Solve has, for example, (-1)^(2/13), which is a radical. Answer

 (-1)^(2/13) This is not a radical expression for example: Solve[X^3 == 1] {{X -> 1}, {X -> -(-1)^(1/3)}, {X -> (-1)^(2/3)}} BUT, ToRadicals[RootReduce[ReIm[X /. Solve[X^3 == 1]]]] {{1, 0}, {-(1/2), -(Sqrt/2)}, {-(1/2), Sqrt/2}} Answer
