    Derivative of e

    I'm trying to find the derivative of the following

    5(e^{-0.01x}-e^{-0.51x})

    Since I thought the derivative of e^x is e^x, I thought that the derivative of the above expression was just itself:

    5(e^{-0.01x}-e^{-0.51x})

    If this is not right, how do I find out the derivative of some exponent with e?

    Either use chain rule to find the derivative or use the formula that the derivative of e^{ax+b} is ae^{ax+b}

    The answer would be -0.05e^{-0.01x}+2.55 e^{-0.51x}
