If A is a 2×2 skew-symmetric matrix with a₁₂ = 5, then A is: A. [[0, 5], [−5, 0]] B. [[0, 5], [5, 0]] C. [[0, −5], [5, 0]] D. [[5, 0], [0, −5]] Answer: A) [[0, 5], [−5, 0]] Explanation: For a 2×2 skew-symmetric matrix, a₁₁ = a₂₂ = 0, and a₂₁ = −a₁₂ = −5. So A = [[0, 5], [−5, 0]].

If A is a 2×2 skew-symmetric matrix with a₁₂ = 5, then A is:

Answer: A) [[0, 5], [−5, 0]]

Explanation: For a 2×2 skew-symmetric matrix, a₁₁ = a₂₂ = 0, and a₂₁ = −a₁₂ = −5. So A = [[0, 5], [−5, 0]].
