I understand that when you use the chain rule you multiply the exponent by the number in front and then reduce the power by 1. So the derivative of 2x^3 = 6x^2(adsbygoogle = window.adsbygoogle || []).push({});

I'm confused now however on how you would solve something like e^-3x, the answer turns out to be -3e^-3x

Am I missing a rule? Why isn't it -3xe^(-3x-1) ?

Thanks in advance
