Homework Help: Writing propositions symbolically

  1. Sep 14, 2011 #1
    1. The problem statement, all variables and given/known data

    For each positive int k, there are k consecutive pos ints that aren't perfect-squares.

    I'm trying to write this in symbolic logic, but am getting messed in the second part and might be a little off on the first.

    2. Relevant equations

    3. The attempt at a solution

    ∀ k > 0 - For each positive int k

    F(k) indicates that k is a not a perfect square. (can this be written symbolically instead?)

    ∀ k > 0 ∃ Fk+1(k) … Fk+k(k).

    If you want to write that symbolically, you could write something like this:

    [tex]F(k) \leftrightarrow k \neq n^2, n \in \mathbb{Z}[/tex]

    Of course, you'd still have to define what Fk+a(k) means.
