Question

If Matrix A has dimensions 2 x 4 and Matrix B has dimensions 1 x 4, can these matrices be multiplied?
YES OR NO

Answer 1

Here's the rule with matrix multiplicaton:

"the inner dimensions must match"

If the inner dimensions match, then the result will be a matrix with the size given by the outer dimensions.

So in this case we have

2 x 4 times 1 x 4

4 and 1 are the inner dimensions
2x (4 1) x4

THEY DON'T MATCH. :( So the multiplication is not possible.

Answer 2

no
