I assume you are asking to find d(e^(g(x)))/dx: the derivative of "e^(g(x))" (Euler's number to the power of some function g(x)) with respect to x. The derivative of e to the power of g(x) with respect to x is the derivative of g(x) times e to the power of g(x). Therefore, d(e^(g(x)))/dx = d(g(x))/dx * e^(g(x))
