Derivation

1. Split input into 2 regimes

2. if k < 2.3579969078137552e+139

   1. Initial program 0.1

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

   3. Applied associate-/l*0.1

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

   4. Applied simplify0.1

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

   if 2.3579969078137552e+139 < k

   1. Initial program 9.4

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

   3. Applied clear-num9.4

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

   4. Applied simplify9.4

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

   5. Taylor expanded around inf 9.4

      \[\leadsto \frac{1}{\color{blue}{10 \cdot \frac{k}{a \cdot e^{-1 \cdot \left(\log \left(\frac{1}{k}\right) \cdot m\right)}} + \left(\frac{1}{e^{-1 \cdot \left(\log \left(\frac{1}{k}\right) \cdot m\right)} \cdot a} + \frac{{k}^{2}}{a \cdot e^{-1 \cdot \left(\log \left(\frac{1}{k}\right) \cdot m\right)}}\right)}}\]

   6. Applied simplify0.5

      \[\leadsto \color{blue}{\frac{1}{(\left(\frac{k}{a}\right) \cdot \left({k}^{\left(-m\right)} \cdot \left(k + 10\right)\right) + \left(\frac{{k}^{\left(-m\right)}}{a}\right))_*}}\]
3. Recombined 2 regimes into one program.
