Let A=\(\begin{bmatrix}2 & -1 & 3\\-4 & 5 & 1\end{bmatrix}\) and B=\(\begin{bmatrix}2 & 3\\4 & -2\\1 & 5\end{bmatrix}\). Which products are defined?

✅ Step-by-Step Solution

Final Answer: Option (C): Both AB and BA
  1. A is 2×3 and B is 3×2. Hence AB is 2×2 and BA is 3×3, so both products are defined.
