\(\frac{\left(x \cdot {z}^{y}\right) \cdot {\left(\sqrt{{a}^{t} \cdot {a}^{\left(-1.0\right)}}\right)}^2}{y \cdot e^{b}}\)
  1. Started with
    \[\frac{x \cdot e^{\left(y \cdot \log z + \left(t - 1.0\right) \cdot \log a\right) - b}}{y}\]
    13.4
  2. Applied simplify to get
    \[\color{red}{\frac{x \cdot e^{\left(y \cdot \log z + \left(t - 1.0\right) \cdot \log a\right) - b}}{y}} \leadsto \color{blue}{\left(\frac{x}{y} \cdot {z}^{y}\right) \cdot \frac{{a}^{\left(t - 1.0\right)}}{e^{b}}}\]
    6.1
  3. Using strategy rm
    6.1
  4. Applied associate-*l/ to get
    \[\color{red}{\left(\frac{x}{y} \cdot {z}^{y}\right)} \cdot \frac{{a}^{\left(t - 1.0\right)}}{e^{b}} \leadsto \color{blue}{\frac{x \cdot {z}^{y}}{y}} \cdot \frac{{a}^{\left(t - 1.0\right)}}{e^{b}}\]
    3.3
  5. Applied frac-times to get
    \[\color{red}{\frac{x \cdot {z}^{y}}{y} \cdot \frac{{a}^{\left(t - 1.0\right)}}{e^{b}}} \leadsto \color{blue}{\frac{\left(x \cdot {z}^{y}\right) \cdot {a}^{\left(t - 1.0\right)}}{y \cdot e^{b}}}\]
    3.3
  6. Using strategy rm
    3.3
  7. Applied add-sqr-sqrt to get
    \[\frac{\left(x \cdot {z}^{y}\right) \cdot \color{red}{{a}^{\left(t - 1.0\right)}}}{y \cdot e^{b}} \leadsto \frac{\left(x \cdot {z}^{y}\right) \cdot \color{blue}{{\left(\sqrt{{a}^{\left(t - 1.0\right)}}\right)}^2}}{y \cdot e^{b}}\]
    3.4
  8. Using strategy rm
    3.4
  9. Applied sub-neg to get
    \[\frac{\left(x \cdot {z}^{y}\right) \cdot {\left(\sqrt{{a}^{\color{red}{\left(t - 1.0\right)}}}\right)}^2}{y \cdot e^{b}} \leadsto \frac{\left(x \cdot {z}^{y}\right) \cdot {\left(\sqrt{{a}^{\color{blue}{\left(t + \left(-1.0\right)\right)}}}\right)}^2}{y \cdot e^{b}}\]
    3.4
  10. Applied unpow-prod-up to get
    \[\frac{\left(x \cdot {z}^{y}\right) \cdot {\left(\sqrt{\color{red}{{a}^{\left(t + \left(-1.0\right)\right)}}}\right)}^2}{y \cdot e^{b}} \leadsto \frac{\left(x \cdot {z}^{y}\right) \cdot {\left(\sqrt{\color{blue}{{a}^{t} \cdot {a}^{\left(-1.0\right)}}}\right)}^2}{y \cdot e^{b}}\]
