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