If A is a square matrix with eigenvalues λ, we can apply induction on the size of the matrix to show that the eigenvalues of A k are λ k for any positive integer k. Hence, the eigenvalues of A 2 are exactly λ 2 (the squares of the eigenvalues of A ). See here: Show that A k has eigenvalues λ k and eigenvectors v.
