To determine whether \( A^n \) is symmetric, skew-symmetric, or neither when \( A \) is a skew-symmetric matrix and \( n \) is an odd natural number, we can follow these steps: ### Step 1: Understand the properties of skew-symmetric matrices A matrix \( A \) is called skew-symmetric if it satisfies the condition: \[ A^T = -A \] where \( A^T \) is the transpose of \( A \). ...
