      \[\leadsto \sqrt{\sqrt{{\color{blue}{\left(\left(n \cdot t\right) \cdot \left(2 \cdot U\right)\right)}}^{2}}} \]

9. Simplified 29.1%

   \[\leadsto \sqrt{\color{blue}{\sqrt{{\left(\left(n \cdot t\right) \cdot \left(2 \cdot U\right)\right)}^{2}}}} \]

10. Taylor expanded in n around -inf 6.2%

    \[\leadsto \sqrt{\color{blue}{-2 \cdot \left(U \cdot \left(n \cdot t\right)\right)}} \]

11. Final simplification 6.2%

    \[\leadsto \sqrt{\left(U \cdot \left(n \cdot t\right)\right) \cdot -2} \]
12. Add Preprocessing
