Which of the following are corect: 1. `A-B=A - (Ann B)` 2. `A = (A nnB) uu (A-B)` 3.`A - (B uu C) =(A-B) uu (A-C)`

A = (A nn B) uu (AB) and A uu (BA) = (A uu B)

A - (B uu C) equals :

Consider the following equations a) A-B=A-(A nn B) b) A=(A nn B)uu(A-B) c) A-(B uu C)=(A-B)uu(A-C) Which of these is / are correct

Which of the following is (A-B) uu(B-A)

A uu B = (AB) uu (BA) uu (A nn B)

A-(B uu C) equals

Prove that A nn(B uu C) =(A nn B) uu (A nn C)

(A uu B) nn (A uu B ^ (c)) = A

Prove that : (A uu B)-C=(A-C) uu (B-C) .
