Answer 1

I can't understand the question can you send us another example

Answer 2

Answer:

A=(1,2,3,4)

B=(3,4,5,6)

C=(4,5,6,7,8)

U=(1,2,3,4,5,6,7,8,9,10)

According to DeMorgan's Law

(A∨B)′=A′∧B′

A′=(∧5,6,7,8,9,10)

B′=(1,2,7,8,9,10)

(A∨B)=3,4

(A∨B)′=1,2,5,6,7,8,9,10

A′∧B′=1,2,5,6,7,8,9,10

Hence proved
