((¬((c∧d)⇔(c∨(b∧c))))∨(b∧((c∧d)∨(¬(c⇒(b∧d))))))⇒b
$$\left(\left(b \wedge \left(\left(c \wedge d\right) \vee c \not\Rightarrow \left(b \wedge d\right)\right)\right) \vee \left(c \wedge d\right) \not\equiv \left(c \vee \left(b \wedge c\right)\right)\right) \Rightarrow b$$
Solución detallada
$$c \vee \left(b \wedge c\right) = c$$
$$\left(c \wedge d\right) ⇔ \left(c \vee \left(b \wedge c\right)\right) = d \vee \neg c$$
$$\left(c \wedge d\right) \not\equiv \left(c \vee \left(b \wedge c\right)\right) = c \wedge \neg d$$
$$c \Rightarrow \left(b \wedge d\right) = \left(b \wedge d\right) \vee \neg c$$
$$c \not\Rightarrow \left(b \wedge d\right) = c \wedge \left(\neg b \vee \neg d\right)$$
$$\left(c \wedge d\right) \vee c \not\Rightarrow \left(b \wedge d\right) = c$$
$$b \wedge \left(\left(c \wedge d\right) \vee c \not\Rightarrow \left(b \wedge d\right)\right) = b \wedge c$$

$$\left(c \wedge d\right) ⇔ \left(c \vee \left(b \wedge c\right)\right) = d \vee \neg c$$
$$\left(c \wedge d\right) \not\equiv \left(c \vee \left(b \wedge c\right)\right) = c \wedge \neg d$$
