    Hey. I made some quick notes for an upcoming test, and just wanted some verification for a few parts. Could somebody please tell me if these are true:

    [tex]y = \log _a f(x) \Rightarrow y' = \frac{{f'(x)}}{{f(x)\ln a}}$[/tex]

    [tex]y = a^{f(x)} \Rightarrow y' = [f'(x)\ln a]e^{f(x)\ln a} $[/tex]


    Thanks,
    Dan.

    I'm pretty sure those are both correct.
