Derivation

  1. Initial program 0.3

    \[e^{-w} \cdot {\ell}^{\left(e^{w}\right)}\]
  2. Using strategy rm

  3. Applied add-sqr-sqrt_binary640.3

    \[\leadsto e^{-w} \cdot {\ell}^{\color{blue}{\left(\sqrt{e^{w}} \cdot \sqrt{e^{w}}\right)}}\]

  4. Applied pow-unpow_binary640.3

    \[\leadsto e^{-w} \cdot \color{blue}{{\left({\ell}^{\left(\sqrt{e^{w}}\right)}\right)}^{\left(\sqrt{e^{w}}\right)}}\]
  5. Using strategy rm

  6. Applied add-cbrt-cube_binary640.3

    \[\leadsto e^{-w} \cdot {\left({\ell}^{\left(\sqrt{e^{w}}\right)}\right)}^{\color{blue}{\left(\sqrt[3]{\left(\sqrt{e^{w}} \cdot \sqrt{e^{w}}\right) \cdot \sqrt{e^{w}}}\right)}}\]

  7. Simplified0.3

    \[\leadsto e^{-w} \cdot {\left({\ell}^{\left(\sqrt{e^{w}}\right)}\right)}^{\left(\sqrt[3]{\color{blue}{{\left(\sqrt{e^{w}}\right)}^{3}}}\right)}\]

  8. Final simplification0.3

    \[\leadsto e^{-w} \cdot {\left({\ell}^{\left(\sqrt{e^{w}}\right)}\right)}^{\left(\sqrt[3]{{\left(\sqrt{e^{w}}\right)}^{3}}\right)}\]
