我有這樣的表達式:X'YZ'+ X'YZ + XY'Z'+ XYZ'+ XYZ('表示不) 我知道答案是Y + XZ',但是我我陷入了最後一部分。任何人都可以幫我一把嗎?使用布爾代數簡化表達式
這是我走到這一步:
X'YZ' + X'YZ + XY'Z' + XYZ' + XYZ
X'YZ' + X'YZ + XZ'(Y' + Y) + XYZ
X'YZ' + X'YZ + XZ' + XYZ
X'YZ' + X'YZ + XYZ + XZ'
Y(X'Z' + X'Z + XZ) + XZ'
Y(1) + XZ' # I am not sure if is there is a rule that makes (X'Z+X'Z+XZ)= 1
感謝
