Solución
Solución detallada
$$x \Rightarrow \left(x \wedge \neg y\right) = \neg x \vee \neg y$$
$$\left(x \Rightarrow \left(x \wedge \neg y\right)\right) \Rightarrow z = z \vee \left(x \wedge y\right)$$
$$\left(x \Rightarrow \left(x \wedge \neg y\right)\right) \not\Rightarrow z = \neg z \wedge \left(\neg x \vee \neg y\right)$$
$$\left(x \wedge y\right) \vee \left(x \Rightarrow \left(x \wedge \neg y\right)\right) \not\Rightarrow z = \left(x \wedge y\right) \vee \neg z$$
$$\left(x \wedge y\right) \vee \neg z$$

Ya está reducido a FND
$$\left(x \wedge y\right) \vee \neg z$$
$$\left(x \vee \neg z\right) \wedge \left(y \vee \neg z\right)$$
$$\left(x \wedge y\right) \vee \neg z$$
