    Solución detallada
    $$\neg \left(a \wedge b\right) = \neg a \vee \neg b$$
    $$\neg \left(b \wedge \neg c\right) = c \vee \neg b$$
    $$\neg \left(a \wedge b\right) \Rightarrow \neg \left(b \wedge \neg c\right) = a \vee c \vee \neg b$$
    $$\neg \left(a \wedge b\right) \not\Rightarrow \neg \left(b \wedge \neg c\right) = b \wedge \neg a \wedge \neg c$$
    $$\neg \left(c \wedge \neg d\right) = d \vee \neg c$$
    $$\neg \left(c \wedge \neg b\right) = b \vee \neg c$$
    $$\neg \left(c \wedge \neg d\right) \Rightarrow \neg \left(c \wedge \neg b\right) = b \vee \neg c \vee \neg d$$
    $$\neg \left(c \wedge \neg d\right) \not\Rightarrow \neg \left(c \wedge \neg b\right) = c \wedge d \wedge \neg b$$
    $$\neg \left(a \wedge b\right) \not\Rightarrow \neg \left(b \wedge \neg c\right) \Rightarrow \neg \left(c \wedge \neg d\right) \not\Rightarrow \neg \left(c \wedge \neg b\right) = a \vee c \vee \neg b$$
    $$\neg \left(d \wedge \neg c\right) = c \vee \neg d$$
    $$\left(\neg \left(a \wedge b\right) \not\Rightarrow \neg \left(b \wedge \neg c\right) \Rightarrow \neg \left(c \wedge \neg d\right) \not\Rightarrow \neg \left(c \wedge \neg b\right)\right) \Rightarrow \neg \left(d \wedge \neg c\right) = c \vee \left(b \wedge \neg a\right) \vee \neg d$$
