I have the following output

Root[-c + λ^6 + 16 λ^4 μ + 
   104 λ^2 μ^2 + 
   384 μ^3 + (14 λ^4 + 168 λ^2 μ + 
      784 μ^2) #1 + (70 λ^2 + 560 μ) #1^2 + 
   140 #1^3 &, 1]

I want to transform the output of the usual form.

  • $\begingroup$ Did you look up what Root means? If yes, that provides the answer. $\endgroup$ – Szabolcs Feb 20 '15 at 16:45

    $\begingroup$ Try Root[-c + \[Lambda]^6 + 16 \[Lambda]^4 \[Mu] + 104 \[Lambda]^2 \[Mu]^2 + 384 \[Mu]^3 + (14 \[Lambda]^4 + 168 \[Lambda]^2 \[Mu] + 784 \[Mu]^2) #1 + (70 \[Lambda]^2 + 560 \[Mu]) #1^2 + 140 #1^3 &, 1] // ToRadicals // FullSimplify. $\endgroup$ – DumpsterDoofus Feb 20 '15 at 16:46
  • $\begingroup$ Thank you. "ToRadicals" is the best answer. $\endgroup$ – Bahram Agheli Feb 20 '15 at 16:55
