 $$\lim_{h \to 0} \dfrac{f(x + h)}{1} * \dfrac{(g(x + h) - g(x))}{h)} + \dfrac{g(x)}{1} *\dfrac{f(x + h) - f(x)}{h} $$
 From here, you can take the limit of each fraction, therefore showing that to find the derivative of two values multiplied together, you can use the formula:
-$$ \dfrac{d}{dx}(f(x) * g(x)) = f(x) * g'(x) + f'(x) $$
-# Natural Exponential Function
-$$ \dfrac{d}{dx} e^x = e^x $$
