Question

If A={6,7,8,9,10}, B={2,4,6,8} and C={3,6,9,12}, prove that: (a) A u (B n C) = (A u B) n ( A u C)​

Answer 1

Answer:

Step-by-step explanation:

B n C= Common elements between b and c. thus the common are: none.

Thus A U ( b n c)= A.

NOw A u B = 2,4,6,7,8,9,10

A u C = 3,6,7,8,9,10,12

NOw going for common in both : 6,7,8,9,10 which is equal to A.

Hence proved
