The problem. Here is the problem: derivative of e to the power x. Find the derivative of e to the power x with respect to x.

Step by step. Exponential rule: d by d x[eᵘ] equals eᵘ times u prime. Combine and simplify.

The answer. So the answer is f prime of x equals e to the power x. The derivative is built from the outside in: sums split into terms, constants factor out, products and quotients use their rules, and every composite function multiplies by the derivative of its inside (chain rule).

Check. Cross-checked numerically against an independent symbolic differentiator at 8 sample points, which checks out.

About derivatives

Differentiate with the power, product, quotient and chain rules, including higher derivatives.
