\({\left(\sqrt[3]{\tan^{-1}_* \frac{im}{re}}\right)}^3\)
  1. Started with
    \[\tan^{-1}_* \frac{im}{re}\]
    0.2
  2. Using strategy rm
    0.2
  3. Applied add-cube-cbrt to get
    \[\color{red}{\tan^{-1}_* \frac{im}{re}} \leadsto \color{blue}{{\left(\sqrt[3]{\tan^{-1}_* \frac{im}{re}}\right)}^3}\]
    0.9
