Question

if A={1, 2,3,4}, B={3,4,5,6} and C={1,2,4,6,7}, then find
A: (AUB) UC​

Answer 1

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

(AUB) = {1, 2,3,4}∪{3,4,5,6}

= {1,2,3,4,5,6}

Now, (AUB) UC = {1,2,3,4,5,6}∪{1,2,4,6,7}

= {1,2,3,4,5,6,7} Ans.

Answer 2

Answer:

Step-by-step explanation:

A={1,2,3,4}

B={3,4,5,6}

C={1,2,4,6,7}

AUB={1,2,3,4}U{3,4,5,6}

AUB={1,2,3,4,5,6}

(AUB) UC​={1,2,3,4,5,6}U{1,2,4,6,7}

(AUB) UC={1,2,3,4,5,6,7}
