Solution to 2008 Problem 95


Angular momentum operators always satisfy the commutation relations
\begin{align*}\left[\hat{J}_x,\hat{J}_y \right] &= i \hbar \hat{J}_z \\\left[\hat{J}_y,\hat{J}_z \right] &= i \hbar \...
So,
\begin{align*}\left[\hat{J}_x \hat{J}_y,\hat{J}_x \right] &= \hat{J}_x \left[ \hat{J}_y,\hat{J}_x \right] + \left[\hat{J}...
Therefore, answer (D) is correct.
