Question

If you can multiply Ax B, then which of the following statements is true about

Answer 1

To multiply B and A, the number of columns of B must matc the number of rows of A.

When we can multiply two matrices?

When we multiply two matrices, A and B, we multiply the rows of matrix A by the columns of matrix B.

Now, the number of elements in a row of a matrix, is equal to the number of columns (and the number of elements in a column is equal to the number of rows).

To multiply BxA:

Then, a row on matrix B must have the same number of elements than a column in row A.

Then, to multiply BxA, the number of columns of B must match the number of rows of A, meaning that the correct option is the last one.
