![**Quantum Mechanics Exercise: Operators on Functions**
Let's explore an interesting exercise in quantum mechanics using operators. You have two functions defined as follows:
- \( g(x) = e^{-ikx} \)
- \( f(x) = e^{-ax^2} \)
There's a function called \( Q(\hat{x}, \hat{p}) \) with some specific rules:
- \( \hat{x} = x \)
- \( \hat{p} = -i\hbar \frac{\partial}{\partial x} \)
Your task is to apply the function \( Q \) by following the standard rules of calculus. Compute the following operations on the specified functions:
a) \( \hat{x}^2 g(x) \)
b) \( \hat{p}^2 f(x) \)
c) \( \hat{p} g(x) \)
d) \( \hat{p} f(x) \)
e) \( \hat{x} \hat{p} g(x) \)
f) \( \hat{p} \hat{x} g(x) \)
h) \( \hat{x} \hat{p} f(x) \)
i) \( \hat{p} \hat{x} f(x) \)
k) Analyze whether the operation of \( \hat{x} \hat{p} \) on a function is always equal to \( \hat{p} \hat{x} \). Provide a justification for your answer.
**Note:** When performing these operations, remember to apply the rules of differentiation and multiplication as dictated by quantum mechanics operators typically pertain to position and momentum in physical systems.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2e50119e-8646-4255-90fd-98958ba58941%2F99ecf0a7-b62c-474d-91f4-3ff97dbabe79%2Frzd9vnn_processed.jpeg&w=3840&q=75)
