WebFind the Derivative - d/dx e^ (-8x) Mathway Calculus Examples Popular Problems Calculus Find the Derivative - d/dx e^ (-8x) e−8x e - 8 x Differentiate using the chain rule, which states that d dx [f (g(x))] d d x [ f ( g ( x))] is f '(g(x))g'(x) f ′ ( g ( x)) g ′ ( x) where f (x) = ex f ( x) = e x and g(x) = −8x g ( x) = - 8 x. Webd dx x n = nx n−1 d dx x 3 = 3x 3−1 = 3x2 (In other words the derivative of x 3 is 3x 2) So it is simply this: "multiply by power then reduce power by 1" It can also be used in cases like this: Example: What is d dx (1/x) ? 1/x is also x-1 We can use the Power Rule, where n = −1: d dx x n = nx n−1 d dx x -1 = −1x -1−1 = −x -2 = −1 x2 how to reset gosund outlets
