Homework Help: Showing that g^-1 H g is a subgroup

  1. Feb 15, 2010 #1
    1. The problem statement, all variables and given/known data
    If H is a subgroup of G, show that [tex]g^{-1}Hg={g^{-1}hg \; h\in H[/tex] is a subgroup for each g[tex]\in[/tex] G


    2. Relevant equations



    3. The attempt at a solution

    I know I just have to check for closure and inverses, but the elements in this group [tex]g^{-1}hg[/tex] with different h or with different g?

    Re: Subgroups

    Same g for all of them but different h's in H.
