x∧y∧z∧(x⇒y)∧(y⇒z)
$$x \wedge y \wedge z \wedge \left(x \Rightarrow y\right) \wedge \left(y \Rightarrow z\right)$$
Solución detallada
$$x \Rightarrow y = y \vee \neg x$$
$$y \Rightarrow z = z \vee \neg y$$
$$x \wedge y \wedge z \wedge \left(x \Rightarrow y\right) \wedge \left(y \Rightarrow z\right) = x \wedge y \wedge z$$
$$y \Rightarrow z = z \vee \neg y$$
$$x \wedge y \wedge z \wedge \left(x \Rightarrow y\right) \wedge \left(y \Rightarrow z\right) = x \wedge y \wedge z$$
