    "Mixed partials" question

    The question and my work are both attached as PDF files.

    Basically, in my work I only found the partial derivatives to be different and therefore did not proceed because of this but apparently this is wrong. Could someone help me figure out what I am doing wrong?

    Any help would be greatly appreciated!
    Thanks in advance!

    I think what you're doing wrong is not writing the words "not exact" in your answer. Your derivatives are fine.
