Let the following fraction be defined with values \( t, n \in \mathbb{N}^{+} \), \( x \in \mathbb{N}^{+} \), \( \mathcal{D}_t \), and \( \mathcal{X}_t \): \[ z = F'(x, t)^{n} + \frac{\partial x}{\partial t} \frac{\mathcal{X}_t + F(x, t) + |x \cdot t|}{\mathcal{D}_t},\\ F(x, t) \neq 0,\\ F'(x, t) \neq 0. \]

The functions \( F(x, t) \) and \( F'(x, t) \) when assumed to be continious have the following relationship \[ F(x, t) \neq F'(x, t) \neq 0. \]
