Chain Rule of a functional to an exponential

In summary, the chain rule of a functional to an exponential is a mathematical rule used to calculate the derivative of a composite function where one function is an exponential and the other is a functional. It is applied by first taking the derivative of the exponential function, and then multiplying it by the derivative of the functional. This rule is important because it allows us to find the derivative of more complex functions and is used in many real-world applications. Some common mistakes when applying this rule include forgetting to multiply the derivatives, applying it in the wrong order, and not simplifying the final result. It can also be extended to higher order derivatives by applying the rule multiple times.

Homework Statement


Suppose f is differentiable on [itex] \mathbb R[/itex] and [itex]\alpha[/itex] is a real number. Let [itex] G(x) = [f(x)]^a[/itex]

Find the expression for [itex] G'(x)[/itex]


Homework Equations



I'm pretty sure that I got this one right, but I really want to double check and make sure.

The Attempt at a Solution



[itex] G'(x) = a[f(x)]^{a-1} \cdot f'(x)[/itex]

That's correct. If you are being precise α ≠ 0.
