What is the transpose of a product AB?

  • A.the transpose of B times the transpose of A
  • B.the transpose of A times the transpose of B
  • C.the product AB unchanged
  • D.the negative of the product BA

Answer: A

The order reverses, which follows from writing out the entries of the product and comparing them with the transposed factors. The same reversal governs the inverse of a product, and forgetting it is a frequent source of error in manipulation.
