Group Theory Proof Help?

  1. Feb 5, 2013 #1
    1. The problem statement, all variables and given/known data

    Here's the question:
    http://assets.openstudy.com/updates...3c487dfb-ceb105-1360099849081-grouptheory.png


    2. Relevant equations



    3. The attempt at a solution

    Step 1: <S,T> subset <<S>,T> subset <<S>,<T>> (easy)
    and Step 2: <S,T> subset <S,<T>> subset <<S>,<T>> (easy)
    and Step 3: <<S>,<T>> subset <S,T> (slightly trickier)

    I've done step 1 and 2 by saying <S> is smallest subgroup of G containing all elements of S and similarly with T.

    No idea how to do step 3 i.e. how to show <<S>,<T>> subset <S,T> ??
