\(\frac{{\left(\sqrt[3]{\frac{x}{e^{b}}}\right)}^3}{\frac{\frac{y}{{z}^{y}}}{{a}^{\left(t - 1.0\right)}}}\)
  1. Started with
    \[\frac{x \cdot e^{\left(y \cdot \log z + \left(t - 1.0\right) \cdot \log a\right) - b}}{y}\]
    13.3
  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
    \[\frac{\color{red}{\frac{x}{e^{b}}}}{\frac{\frac{y}{{z}^{y}}}{{a}^{\left(t - 1.0\right)}}} \leadsto \frac{\color{blue}{{\left(\sqrt[3]{\frac{x}{e^{b}}}\right)}^3}}{\frac{\frac{y}{{z}^{y}}}{{a}^{\left(t - 1.0\right)}}}\]
    3.6
