Question

solve the following question... question from matrices..​

Answer 1

Answer:

AP= $\left[\begin{array}{ccc}33&0&0\\0&33&0\\0&0&33\end{array}\right]$

Step-by-step explanation:

$\left[\begin{array}{ccc}2&3&1\\1&-1&2\\3&1&-3\end{array}\right]$$\left[\begin{array}{ccc}1&10&7\\9&-9&-3\\4&7&-5\end{array}\right]$

on multiplying both the matrices like

(2x1)+3x9+1x4     2x10+3(-9)+1x7     2x7+3(-3)+1(-5)

1-9+8                         10+9+14                7+3-10

3+9-12                         30-9-21                21-3+15

Finally we get AP=

$\left[\begin{array}{ccc}33&0&0\\0&33&0\\0&0&33\end{array}\right]$
