    No it's not. You've got to differentiate with respect to x by the way.

    It's not differentiating e, differentiating with respect to x.

    The answer is ye^(xy). You have to use the chain rule:

    First, differentiate the "argument" of the function (in this case, xy) to give y. Then, differentiate the function itself, leaving the argument the same (and as you should know, the derivative of an exponential is still an exponential). Multiply the two answers to give ye^(xy).



    I never add friend codes.
