Question

What is the product?

Answer 1

Answer:

Step-by-step explanation:

$\begin{bmatrix}3 & 6 & 1\\ 2 & 4& 0\\ 0 & 6 & 2\end{bmatrix}\times\begin{bmatrix}2\\ 0\\ 1\end{bmatrix}$

Multiply the terms of the rows of the first matrix with the terms given in the column of the second matrix.

$=\begin{bmatrix}(3\times 2+6\times 0+1\times 1)\\ (2\times 2+4\times 0+0\times1)\\ (0\times 2+6\times 0+2\times 1)\end{bmatrix}$

$=\begin{bmatrix}7\\ 4\\ 2\end{bmatrix}$
