(x∧y)∨((¬(x⇒(x∧(¬y))))⇒z)
$$\left(x \wedge y\right) \vee \left(x \not\Rightarrow \left(x \wedge \neg y\right) \Rightarrow z\right)$$
Solución detallada
$$x \Rightarrow \left(x \wedge \neg y\right) = \neg x \vee \neg y$$
$$x \not\Rightarrow \left(x \wedge \neg y\right) = x \wedge y$$
$$x \not\Rightarrow \left(x \wedge \neg y\right) \Rightarrow z = z \vee \neg x \vee \neg y$$
$$\left(x \wedge y\right) \vee \left(x \not\Rightarrow \left(x \wedge \neg y\right) \Rightarrow z\right) = 1$$
$$x \not\Rightarrow \left(x \wedge \neg y\right) = x \wedge y$$
$$x \not\Rightarrow \left(x \wedge \neg y\right) \Rightarrow z = z \vee \neg x \vee \neg y$$
$$\left(x \wedge y\right) \vee \left(x \not\Rightarrow \left(x \wedge \neg y\right) \Rightarrow z\right) = 1$$
