If A is a skew-symmetric matrix, then `A^(2)` is a .................

Explanation

To determine the nature of \( A^2 \) when \( A \) is a skew-symmetric matrix, we can follow these steps:

### Step-by-step Solution:

1. **Definition of Skew-Symmetric Matrix**:
A matrix \( A \) is skew-symmetric if it satisfies the condition:
\[
A = -A^T
