Question

What is the product?

Answer 1

Explanation:

`\begin{bmatrix}3 & 6 & 1\\ 2 & 4& 0\\ 0 & 6 & 2\end{bmatrix}*\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* 2+6* 0+1* 1)\\ (2* 2+4* 0+0*1)\\ (0* 2+6* 0+2* 1)\end{bmatrix}`

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