How to prove this?

  1. Sep 20, 2011 #1
    If [tex]a^x|b^y[/tex] & [tex]xt-yz\geq 0[/tex] then [tex]a^z|b^t[/tex]

    This is not a homework. I found this theorem in a book without having proved it, so I wondered how it could be proved.

    The trick is to realise that:

    if xt >= yz, then b^(yz) | b^(xt)
