    Solución

    Ha introducido [src] 
    ¬((a⇒(b∧c))⇒d)
    (a⇒(b∧c))⇏d\left(a \Rightarrow \left(b \wedge c\right)\right) \not\Rightarrow d
    Solución detallada
    a⇒(b∧c)=(b∧c)∨¬aa \Rightarrow \left(b \wedge c\right) = \left(b \wedge c\right) \vee \neg a
    (a⇒(b∧c))⇒d=d∨(a∧¬b)∨(a∧¬c)\left(a \Rightarrow \left(b \wedge c\right)\right) \Rightarrow d = d \vee \left(a \wedge \neg b\right) \vee \left(a \wedge \neg c\right)
    (a⇒(b∧c))⇏d=¬d∧(b∨¬a)∧(c∨¬a)\left(a \Rightarrow \left(b \wedge c\right)\right) \not\Rightarrow d = \neg d \wedge \left(b \vee \neg a\right) \wedge \left(c \vee \neg a\right)
    Simplificación [src]
    ¬d∧(b∨¬a)∧(c∨¬a)\neg d \wedge \left(b \vee \neg a\right) \wedge \left(c \vee \neg a\right)
