Confusion about d/dx(e^x)

Hello, in my Math Class i was taught that d/dx(e^x) = e^x. This calculator is adding *ln(e) why would that be?

Also d/dax(e^(a*x)) = e^(a*x)*ln(e) but d/dx(e^(3*x))= 3e^(3x)*ln(e)
So shouldn´t d/dax(...) be a*e^(a*x)*ln(e) read more ..

Hello, if i want the Differential from "log10(ax)" what happens to the a ? i would guess "1/a*x*ln(10)" but i am not sure because in the diff from "ln(ax)" the a fades away because "a*1/a*X"
