# Use the laws of set algebra to prove m AanB):

Any guidance would be greatly appreciated

For i)

A ∪ (A' ∩ B) = A ∪ B

LHS= A ∪ (A' ∩ B)

= (A ∪ A') ∩ (A ∪ B)

= U ∩ (A ∪ B)

= A ∪ B

= RHS

Is that right?

For the second question I am confused how to work with that many complements?

A ∪ (( B' ∩ A) ∩ A'= U

How do I tackle this?

Thankyou
