Questions & Answers
Q: What formulas are needed to solve this derivative problem?
The product rule and the formula for the derivative of a function with respect to x of a to the x are necessary to solve this problem.
Q: What is the product rule?
The product rule states that when finding the derivative of the product of two functions, we differentiate the first function multiplied by the second function, and then add the first function multiplied by the derivative of the second function.
Q: How does the chain rule apply in this problem?
The chain rule is applied when differentiating the outside function evaluated at the inside function. Here, the outside function is 5 to the negative alpha over 2, and the inside function is negative alpha over 2.
Q: What are the derivatives of the outside and inside functions?
The derivative of the outside function is 5 to the negative alpha over 2 times ln5, and the derivative of the inside function is negative one-half.
