  1. Step-by-step explanation:

    Answer

    Open in answr app

    The given sets are:

    A={1,2,4,5}, B={2,3,5,6}, C={4,5,6,7}

    ∴ B∪C={2,3,4,5,6,7}

    A−(B∪C)={1}

    A−B={1,4}

    A−C={1,2}

    (A−B)∩(A−C)={1}

    we have to verify, A−(B∪C)=(A−B)∩(A−C)

    LHS=A−(A∪C)

    ={1}

    RHS=(A−B)∩(A−C)

    ={1}

    Hence, A−(B∪C)=(A−B)∩(A−C)
