  1. Started with
    \[\frac{x \cdot e^{\left(y \cdot \log z + \left(t - 1.0\right) \cdot \log a\right) - b}}{y}\]
    13.0
  2. Applied simplify to get
    \[\color{red}{\frac{x \cdot e^{\left(y \cdot \log z + \left(t - 1.0\right) \cdot \log a\right) - b}}{y}} \leadsto \color{blue}{\frac{\frac{x}{e^{b}}}{\frac{\frac{y}{{z}^{y}}}{{a}^{\left(t - 1.0\right)}}}}\]
    3.5
  3. Using strategy rm
    3.5
  4. Applied add-cube-cbrt to get
    \[\frac{\frac{x}{e^{b}}}{\frac{\frac{y}{{z}^{y}}}{\color{red}{{a}^{\left(t - 1.0\right)}}}} \leadsto \frac{\frac{x}{e^{b}}}{\frac{\frac{y}{{z}^{y}}}{\color{blue}{{\left(\sqrt[3]{{a}^{\left(t - 1.0\right)}}\right)}^3}}}\]
    3.5
  5. Applied add-cube-cbrt to get
    \[\frac{\frac{x}{e^{b}}}{\frac{\color{red}{\frac{y}{{z}^{y}}}}{{\left(\sqrt[3]{{a}^{\left(t - 1.0\right)}}\right)}^3}} \leadsto \frac{\frac{x}{e^{b}}}{\frac{\color{blue}{{\left(\sqrt[3]{\frac{y}{{z}^{y}}}\right)}^3}}{{\left(\sqrt[3]{{a}^{\left(t - 1.0\right)}}\right)}^3}}\]
    3.6
  6. Applied cube-undiv to get
    \[\frac{\frac{x}{e^{b}}}{\color{red}{\frac{{\left(\sqrt[3]{\frac{y}{{z}^{y}}}\right)}^3}{{\left(\sqrt[3]{{a}^{\left(t - 1.0\right)}}\right)}^3}}} \leadsto \frac{\frac{x}{e^{b}}}{\color{blue}{{\left(\frac{\sqrt[3]{\frac{y}{{z}^{y}}}}{\sqrt[3]{{a}^{\left(t - 1.0\right)}}}\right)}^3}}\]
    3.6
  7. Applied add-cube-cbrt to get
    \[\frac{\color{red}{\frac{x}{e^{b}}}}{{\left(\frac{\sqrt[3]{\frac{y}{{z}^{y}}}}{\sqrt[3]{{a}^{\left(t - 1.0\right)}}}\right)}^3} \leadsto \frac{\color{blue}{{\left(\sqrt[3]{\frac{x}{e^{b}}}\right)}^3}}{{\left(\frac{\sqrt[3]{\frac{y}{{z}^{y}}}}{\sqrt[3]{{a}^{\left(t - 1.0\right)}}}\right)}^3}\]
    3.6
  8. Applied cube-undiv to get
    \[\color{red}{\frac{{\left(\sqrt[3]{\frac{x}{e^{b}}}\right)}^3}{{\left(\frac{\sqrt[3]{\frac{y}{{z}^{y}}}}{\sqrt[3]{{a}^{\left(t - 1.0\right)}}}\right)}^3}} \leadsto \color{blue}{{\left(\frac{\sqrt[3]{\frac{x}{e^{b}}}}{\frac{\sqrt[3]{\frac{y}{{z}^{y}}}}{\sqrt[3]{{a}^{\left(t - 1.0\right)}}}}\right)}^3}\]
