\((b * \left(a \cdot i - c \cdot z\right) + \left((\left(t \cdot c - i \cdot y\right) * j + \left(x \cdot \left(y \cdot z - a \cdot t\right)\right))_*\right))_*\)
  1. Started with
    \[\left(x \cdot \left(y \cdot z - t \cdot a\right) - b \cdot \left(c \cdot z - i \cdot a\right)\right) + j \cdot \left(c \cdot t - i \cdot y\right)\]
    5.3
  2. Applied simplify to get
    \[\color{red}{\left(x \cdot \left(y \cdot z - t \cdot a\right) - b \cdot \left(c \cdot z - i \cdot a\right)\right) + j \cdot \left(c \cdot t - i \cdot y\right)} \leadsto \color{blue}{(\left(c \cdot t - i \cdot y\right) * j + \left(\left(y \cdot z - t \cdot a\right) \cdot x\right))_* - b \cdot \left(c \cdot z - i \cdot a\right)}\]

  3. Using strategy rm
    5.3
  4. Applied add-cube-cbrt to get
    \[\color{red}{(\left(c \cdot t - i \cdot y\right) * j + \left(\left(y \cdot z - t \cdot a\right) \cdot x\right))_* - b \cdot \left(c \cdot z - i \cdot a\right)} \leadsto \color{blue}{{\left(\sqrt[3]{(\left(c \cdot t - i \cdot y\right) * j + \left(\left(y \cdot z - t \cdot a\right) \cdot x\right))_* - b \cdot \left(c \cdot z - i \cdot a\right)}\right)}^3}\]
    5.7
  5. Applied taylor to get
    \[{\left(\sqrt[3]{(\left(c \cdot t - i \cdot y\right) * j + \left(\left(y \cdot z - t \cdot a\right) \cdot x\right))_* - b \cdot \left(c \cdot z - i \cdot a\right)}\right)}^3 \leadsto {\left(\sqrt[3]{\left((\left(c \cdot t - y \cdot i\right) * j + \left(\left(y \cdot z - t \cdot a\right) \cdot x\right))_* + b \cdot \left(a \cdot i\right)\right) - b \cdot \left(c \cdot z\right)}\right)}^3\]
    5.7
  6. Taylor expanded around 0 to get
    \[{\color{red}{\left(\sqrt[3]{\left((\left(c \cdot t - y \cdot i\right) * j + \left(\left(y \cdot z - t \cdot a\right) \cdot x\right))_* + b \cdot \left(a \cdot i\right)\right) - b \cdot \left(c \cdot z\right)}\right)}}^3 \leadsto {\color{blue}{\left(\sqrt[3]{\left((\left(c \cdot t - y \cdot i\right) * j + \left(\left(y \cdot z - t \cdot a\right) \cdot x\right))_* + b \cdot \left(a \cdot i\right)\right) - b \cdot \left(c \cdot z\right)}\right)}}^3\]
    5.7
  7. Applied simplify to get
    \[{\left(\sqrt[3]{\left((\left(c \cdot t - y \cdot i\right) * j + \left(\left(y \cdot z - t \cdot a\right) \cdot x\right))_* + b \cdot \left(a \cdot i\right)\right) - b \cdot \left(c \cdot z\right)}\right)}^3 \leadsto (b * \left(a \cdot i - c \cdot z\right) + \left((\left(t \cdot c - i \cdot y\right) * j + \left(x \cdot \left(y \cdot z - a \cdot t\right)\right))_*\right))_*\]
