Question

If A = {1, 2, 4} and B = {2, 4,5} , C = {2,5} ,then find (A -B) X ( B-C)​

Answer 1

Step-by-step explanation:

A={1,2,4}, B={2,4,5}, C={2,5}

A−C={1,4}

B−C={4}

(A−C)×(B−C)={1,4}×{4}

={1,4},{4,4}.

Answer 2

Answer:

LHS

A-B= {1,2,4} - {2,4,5}

={1,5}

B-C={2,4,5} - {2,5}

={4}

(A-B) X (B-C) = {1,5} X {4}

={(1,4) (5,4)}
