Derivation

  1. Initial program 0.1

    \[\left(d1 \cdot \left(\left(\left(\left(\left(d1 \cdot \left(d1 \cdot d1\right)\right) \cdot d1\right) \cdot d1\right) \cdot \left(d1 \cdot d1\right)\right) \cdot d1\right)\right) \cdot d1\]

  2. Taylor expanded around inf 0.1

    \[\leadsto \left(d1 \cdot \left(\color{blue}{{d1}^{7}} \cdot d1\right)\right) \cdot d1\]

  3. Applied simplify0.1

    \[\leadsto \color{blue}{{d1}^{3} \cdot {d1}^{7}}\]
  4. Using strategy rm

  5. Applied pow-prod-up0

    \[\leadsto \color{blue}{{d1}^{\left(3 + 7\right)}}\]
