(a) m0 + m1 + m5 + m7
Mapping the given function in a K-map, we get 2 Pairs i.e., Pair-1 is m0 + m1 and Pair-2 is m5 + m7
= X’Y’Z’ + X’Y’Z + XY’Z + XYZ
= X’Y’(Z’ + Z) + XZ(Y’ + Y)
= X’Y’ + XZ
Simplified Boolean expression for given K-map is F(X, Y, Z) = X’Y’ + XZ.
(b) F = ∑(1, 3, 5, 4, 7)
Mapping the given function in a K-map, we get 1 Pair and 1 Quad i.e., Pair is m4 + m5 and Quad is m1 + m3 + m5 + m7
= X’Y’Z + X’YZ + XY’Z + XYZ + XY’Z’ + XY’Z
= X’Z(Y’ + Y) + XZ(Y’ + Y) + XY’(Z’ + Z)
= X’Z + XZ + XY’ = Z(X’ + X) + XY’
= Z + XY’
Simplified Boolean expression as for given K-map is F(X, Y, Z) = Z + XY’.
(c) m0 +m2 + m4 + m6
Mapping the given function in a K-map, we get 2 Pairs i.e., Pair-1 is m0 + m4 and Pair-2 is m2 + m6
= X’Y’Z’ + XY’Z’ + X’YZ’ + XYZ’
= Y’Z’(X’ + X) + YZ’(X’ + X) = Y’Z’ + YZ’
= Z’(Y’ + Y) = Z’
Simplified Boolean expression for given K-map is F(X, Y, Z) = Z’.
