To evaluate this derivative you use the product rule When you have a function that is the product of 2 functions f x and g x you can derive it as d dx f x g x f x g x f x g x In your case f x x and f x 1 g x e x and g x e x Finally deriving the complete function we have d dx xe x 1e x xe x e x x 1 D dx b x b x lnb First note that b x e ln b x e xlnb This allows us to differentiate the function using the chain rule d dx e xlnb e xlnb d dx xlnb Just like d dx 5x 5 d dx xlnb lnb since lnb will always be a constant This gives us a derivative of e xlnb lnb Now recall that e xlnb b x This gives us our final differentiated result
We use a technique called logarithmic differentiation to differentiate this kind of function In short we let y cos x x Then ln y ln cos x x ln y The answer is y ex e 1 It s a power function Calculus Differentiating Exponential Functions Differentiating Exponential Functions with Other Bases

For the function f x x n n should not equal 0 for reasons which will become clear n should also be an integer or a rational number i e a fraction The rule is f x x n f x nx n 1 In other words we borrow the power of x and make it the coefficient of the derivative and then subtract 1 from the power f x x 2 f x 2x 1 f x x 7 f x D dx 4 x 4 x ln4 In general for b 0 we have d dx b x b x lnb And when we need the chain rule we have d dx b u b u lnb d dx u Proof of General rule b x e lnb x remember that e lnu u So b x e xlnb because a r s a rs a sr d dx e xlnb can be found by the chain rule d dx e xlnb e xlnb d dx xlnb e xlnb lnb lnb is a
