Question

If possible, find AB. & State the dimension of the result.

Answer 1

Explanation:

`A=\begin{bmatrix}0 &0 &5 \\ 0 &0 &-3 \\ 0 &0 &3 \end{bmatrix}`

`B=\begin{bmatrix}8 &-12 &5 \\ 7 &19 &5 \\ 0 &0 &0 \end{bmatrix}`

A.B = A × B

`A.B=\begin{bmatrix}0 &0 &0 \\ 0 &0 &0 \\ 0 &0 &0 \end{bmatrix}`

Dimension of the resultant matrix is (3 × 3)
