Question

If A={1,2,3,4}, B={3,4,5,6,7,8}, C={4,5,6,7,8} set X={1,2,3,4,5,6,7,8,9,10}then verify the following: A] A U B(B n C )= (A U B) intersection (A U C)

Answer 1

a

$a \: u \: b = 12345678 \\ a \: u \: c = 12345678 \\ a \: n \: b = < 12345678 >$

Answer 2

A U B={1,2,3,4,5,6,7,8}

B n C={4,5,6,7,8}

A U B={1,2,3,4,5,6,7,8}

A U C={1,2,3,4,5,6,7,8}
