\(\frac{\left(x \cdot {z}^{y}\right) \cdot \frac{{a}^{t} \cdot {a}^{\left(-1.0\right)}}{e^{b}}}{y}\)
  1. Started with
    \[\frac{x \cdot e^{\left(y \cdot \log z + \left(t - 1.0\right) \cdot \log a\right) - b}}{y}\]
    29.2
  2. Applied simplify to get
    \[\color{red}{\frac{x \cdot e^{\left(y \cdot \log z + \left(t - 1.0\right) \cdot \log a\right) - b}}{y}} \leadsto \color{blue}{\left(\frac{x}{y} \cdot {z}^{y}\right) \cdot \frac{{a}^{\left(t - 1.0\right)}}{e^{b}}}\]
    7.2
  3. Using strategy rm
    7.2
  4. Applied associate-*l/ to get
    \[\color{red}{\left(\frac{x}{y} \cdot {z}^{y}\right)} \cdot \frac{{a}^{\left(t - 1.0\right)}}{e^{b}} \leadsto \color{blue}{\frac{x \cdot {z}^{y}}{y}} \cdot \frac{{a}^{\left(t - 1.0\right)}}{e^{b}}\]
    7.2
  5. Applied associate-*l/ to get
    \[\color{red}{\frac{x \cdot {z}^{y}}{y} \cdot \frac{{a}^{\left(t - 1.0\right)}}{e^{b}}} \leadsto \color{blue}{\frac{\left(x \cdot {z}^{y}\right) \cdot \frac{{a}^{\left(t - 1.0\right)}}{e^{b}}}{y}}\]
    1.7
  6. Using strategy rm
    1.7
  7. Applied sub-neg to get
    \[\frac{\left(x \cdot {z}^{y}\right) \cdot \frac{{a}^{\color{red}{\left(t - 1.0\right)}}}{e^{b}}}{y} \leadsto \frac{\left(x \cdot {z}^{y}\right) \cdot \frac{{a}^{\color{blue}{\left(t + \left(-1.0\right)\right)}}}{e^{b}}}{y}\]
    1.7
  8. Applied unpow-prod-up to get
    \[\frac{\left(x \cdot {z}^{y}\right) \cdot \frac{\color{red}{{a}^{\left(t + \left(-1.0\right)\right)}}}{e^{b}}}{y} \leadsto \frac{\left(x \cdot {z}^{y}\right) \cdot \frac{\color{blue}{{a}^{t} \cdot {a}^{\left(-1.0\right)}}}{e^{b}}}{y}\]
