1.	A is a matrix of order 2×mand B is a matrix of order 3×n such that both AB and BA are defined. Is AB−BA defined ?
Answer» Answer: Since AB EXISTS, so the NUMBER of column in A= Number of column in B. So B has n row. Since BA exists, so the number of column in B= Number of column in A. So B has m column. ∴ B is an n×m matrix. Step-by-step explanation: HOPE THIS HELPS PLEASE MARK AS BRAINLIEST.

Answer:

Since AB EXISTS, so the NUMBER of column in A= Number of column in B.

So B has n row.

Since BA exists, so the number of column in B= Number of column in A.

So B has m column.

∴ B is an n×m matrix.
