Derivation

1. Initial program 12.4

   \[\left(\left(3 + \frac{2}{r \cdot r}\right) - \frac{\left(0.125 \cdot \left(3 - 2 \cdot v\right)\right) \cdot \left(\left(\left(w \cdot w\right) \cdot r\right) \cdot r\right)}{1 - v}\right) - 4.5\]

2. Applied simplify0.4

   \[\leadsto \color{blue}{\left(\frac{2}{r \cdot r} + 3\right) - (\left(\frac{0.125}{1 - v} \cdot \left(\left(3 - v\right) - v\right)\right) \cdot \left(\left(w \cdot r\right) \cdot \left(w \cdot r\right)\right) + 4.5)_*}\]
3. Using strategy rm

4. Applied add-cbrt-cube0.4

   \[\leadsto \left(\frac{2}{r \cdot r} + 3\right) - (\color{blue}{\left(\sqrt[3]{\left(\left(\frac{0.125}{1 - v} \cdot \left(\left(3 - v\right) - v\right)\right) \cdot \left(\frac{0.125}{1 - v} \cdot \left(\left(3 - v\right) - v\right)\right)\right) \cdot \left(\frac{0.125}{1 - v} \cdot \left(\left(3 - v\right) - v\right)\right)}\right)} \cdot \left(\left(w \cdot r\right) \cdot \left(w \cdot r\right)\right) + 4.5)_*\]

5. Applied simplify0.4

   \[\leadsto \left(\frac{2}{r \cdot r} + 3\right) - (\left(\sqrt[3]{\color{blue}{{\left(\left(\left(3 - v\right) - v\right) \cdot \frac{0.125}{1 - v}\right)}^{3}}}\right) \cdot \left(\left(w \cdot r\right) \cdot \left(w \cdot r\right)\right) + 4.5)_*\]
