Derivation

  1. Initial program 2.1

    \[\frac{a \cdot {k}^{m}}{\left(1 + 10 \cdot k\right) + k \cdot k}\]
  2. Simplified2.1

    \[\leadsto \color{blue}{\frac{{k}^{m} \cdot a}{1 + k \cdot \left(k + 10\right)}}\]
  3. Using strategy rm
  4. Applied div-inv2.1

    \[\leadsto \color{blue}{\left({k}^{m} \cdot a\right) \cdot \frac{1}{1 + k \cdot \left(k + 10\right)}}\]
  5. Final simplification2.1

    \[\leadsto \left({k}^{m} \cdot a\right) \cdot \frac{1}{1 + \left(k + 10\right) \cdot k}\]
