    For future questions, this notation might be helpful.

    "5to the 2nd power" is typed as 5^2 and read as "5 squared." However, with your question, it is hard to tell if you mean (17-5)^2 or just 5^2.

    This is a rephrasing of your question:

    (17 -5^2)/(2^4 + 3^2) = (17 + 25)/(16 + 9) = 42/25 = 1.68 (Remember that a negative times a negative becomes a positive.)

    With the other interpretation, it
    is:

    (17-5)^2/(2^4 + 3^2) = (12^2)/25 = 144/25 = 5.76

    I don't know how Zoey got 18.

    I hope this helps. Thanks for asking.
