    Do you know where can I find proven identity
    [tex]det(AB)=det(A)det(B)[/tex]
    using Levi Civita symbol.

    You can find a proof in "Linear Algebra" by Lang. He doesn't exactly use the Levi-Civita symbol, but he rathers works with signs of permutations. But this is of course almost the same as the Levi-Civita symbol, so it should be very easy to rewrite the proof.
