Derivation

  1. Initial program 33.7

    \[\frac{\sqrt{p} \cdot q}{\sqrt{p + \left(q - r\right) \cdot \left(\left(q - r\right) + \sqrt{p + \left(q - r\right) \cdot \left(q - r\right)}\right)}}\]

  2. Final simplification33.7

    \[\leadsto \frac{\sqrt{p} \cdot q}{\sqrt{p + \left(q - r\right) \cdot \left(\left(q - r\right) + \sqrt{p + \left(q - r\right) \cdot \left(q - r\right)}\right)}}\]
