\(\frac{\left(\left({y}^{4} \cdot x + \left(y \cdot y\right) \cdot 27464.7644705\right) + \left(t + {y}^3 \cdot z\right)\right) + y \cdot 230661.510616}{i + \left(\left(c + b \cdot y\right) + \left(y \cdot y\right) \cdot \left(a + y\right)\right) \cdot y}\)
  1. Started with
    \[\frac{\left(\left(\left(x \cdot y + z\right) \cdot y + 27464.7644705\right) \cdot y + 230661.510616\right) \cdot y + t}{\left(\left(\left(y + a\right) \cdot y + b\right) \cdot y + c\right) \cdot y + i}\]
