    Integral of Exponential functions (a^x)

    can anyone shows me why
    d(a^x)/(dx) = In(a)a^x

    and

    d(a^-x)/(dx) = -In(a)a^-x

    ??

    Thanks!

    \frac{da^{x}}{dx}=\frac{de^{\ln(a)x}}{dx}=\ln(a)e^ {\ln(a)x}=\ln(a)a^{x}

    By the way is it derivitave or integral?
    Thanks from sweetadam
