Help solve the Absorption Law

  1. Sep 7, 2009 #1
    1. The problem statement, all variables and given/known data

    prove that A v (B ^ A) = A

    2. Relevant equations

    V = union
    ^ = intersection
    ' = complement

    3. The attempt at a solution

    A v (B ^ A) = (A v B) ^ (A v A) (used distributive property)


    ummm yeah im kinda lost from here. much help appreciated

    Try

    [tex]A \vee (A \wedge B) = (A \wedge \bold{U}) \vee (A \wedge B)[/tex]

    and work from there. (Note that U is the universe.)
