(¬(a∨(a∧b)))∧(a∨(b∧(¬a)))
$$\neg \left(a \vee \left(a \wedge b\right)\right) \wedge \left(a \vee \left(b \wedge \neg a\right)\right)$$
Solución detallada
$$a \vee \left(a \wedge b\right) = a$$
$$\neg \left(a \vee \left(a \wedge b\right)\right) = \neg a$$
$$a \vee \left(b \wedge \neg a\right) = a \vee b$$
$$\neg \left(a \vee \left(a \wedge b\right)\right) \wedge \left(a \vee \left(b \wedge \neg a\right)\right) = b \wedge \neg a$$
$$\neg \left(a \vee \left(a \wedge b\right)\right) = \neg a$$
$$a \vee \left(b \wedge \neg a\right) = a \vee b$$
$$\neg \left(a \vee \left(a \wedge b\right)\right) \wedge \left(a \vee \left(b \wedge \neg a\right)\right) = b \wedge \neg a$$
