Find the product.
[5 5];[-2 3]*[-4 9];[8 7]
1 answer
The product of [5 5];[-2 3] and [-4 9];[8 7] is not defined because matrix multiplication is only defined for matrices with compatible dimensions. In this case, the first matrix has dimensions 2x2 and the second matrix has dimensions 2x2, so matrix multiplication is not possible.
