comment How to apply Vandemonde determinant to show nilpotent here?
Let $\mu_1, \ldots, \mu_k$ be non-zero distinct eigenvalues and $m_1, \ldots, m_k$ their multiplicities. Now you can interpret $\sum_i \mu_i^k m_i = 0$ as system of equations in unknowns $m_i$. What's the determinant of this system?
