Expresión xy∨(¯(x→x¬y)→z)

El profesor se sorprenderá mucho al ver tu solución correcta😉

    Solución

    Ha introducido [src]
    (x∧y)∨(¬((x⇒(x∧(¬y)))⇒z))
    $$\left(x \wedge y\right) \vee \left(x \Rightarrow \left(x \wedge \neg y\right)\right) \not\Rightarrow z$$
    Solución detallada
    $$x \Rightarrow \left(x \wedge \neg y\right) = \neg x \vee \neg y$$
    $$\left(x \Rightarrow \left(x \wedge \neg y\right)\right) \Rightarrow z = z \vee \left(x \wedge y\right)$$
    $$\left(x \Rightarrow \left(x \wedge \neg y\right)\right) \not\Rightarrow z = \neg z \wedge \left(\neg x \vee \neg y\right)$$
    $$\left(x \wedge y\right) \vee \left(x \Rightarrow \left(x \wedge \neg y\right)\right) \not\Rightarrow z = \left(x \wedge y\right) \vee \neg z$$
    Simplificación [src]
    $$\left(x \wedge y\right) \vee \neg z$$
    (¬z)∨(x∧y)
