# Math Help - Integral of Exponential functions (a^x)

1. ## 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!

2. Look here Derivative b^x

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

By the way is it derivitave or integral?
