Solución detallada
$$b ⊕ c = \left(b \wedge \neg c\right) \vee \left(c \wedge \neg b\right)$$
$$\neg \left(b ⊕ c\right) = \left(b \wedge c\right) \vee \left(\neg b \wedge \neg c\right)$$
$$a \wedge \neg \left(b ⊕ c\right) = a \wedge \left(b \vee \neg c\right) \wedge \left(c \vee \neg b\right)$$
$$a \wedge \left(b \vee \neg c\right) \wedge \left(c \vee \neg b\right)$$
