Question

Use the matrix to preform the scalar multiplication , 5A

Answer 1

`\displaystyle \left[\begin{array}{ccc}15&25\\10&55\end{array}\right]`

Explanation:

In this case, we multiply each element in the matrix by 5:

`\displaystyle 5A=5\left[\begin{array}{ccc}3&5\\2&11\end{array}\right]=\left[\begin{array}{ccc}5*3&5*5\\2*5&11*5\end{array}\right]=\left[\begin{array}{ccc}15&25\\10&55\end{array}\right]`
