Question

What is the product? 1/2 . [12 64 78 30 ]

Answer 1

`\left[\begin{array}{c c c c}6 & 32 & 39 & 15\end{array}\right]`

Explanation:

When multiplying a constant by a matrix, we have to multiply each element by the constant.

`(1)/(2) \cdot \left[\begin{array}{c c c c}12 & 64 & 78 & 30\end{array}\right]`

`= \left[\begin{array}{c c c c} (12)/(2) & (64)/(2) & (78)/(2) & (30)/(2)\end{array}\right]`

`= \left[\begin{array}{c c c c}6 & 32 & 39 & 15\end{array}\right]`
