Homework Help: Determining If An Element Is Part Of A Set

  1. Sep 27, 2012 #1
    The question is, "determine whether 2 is a set of the following," the set being
    {x∈R|x is the square of an integer}

    I think I might need a bit of help interpreting the meaning; I believe its saying that if you square some number, you'll get x, right? I just need a little help reading this.
