Please help me with this problem clearly and with step by step explanation please.. NEEDED BOTH PLEASE
![3.* Show that (A \ B) \ C = A \ (BUC). Is (A \ B)\C = A\ (B\C)?
4.* If A and B are sets, we define their symmetric difference as
ΑΔΒ = Α } Β) υ (B] Α) .
Prove that AAB=Ø if and only if A = B.
(Hint: remember that to prove an “if and only if" statement, you need to prove two implications,
one in each direction)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8b2daeeb-71d1-4d55-9248-1f06d15ca0d9%2Fd7ff9b1f-2dc5-48b1-a4a6-670ed12ee7ad%2Fwfmldjj_processed.jpeg&w=3840&q=75)
