Answer 2

$B-5 A=$$\left[\begin{array}{ccc}7 & -17 & -37 \\-39 & -11 & -26\end{array}\right]$

விளக்கம்:

$A=\left[\begin{array}{lll}0 & 4 & 9 \\8 & 3 & 7\end{array}\right]$

$B=\left[\begin{array}{lll}7 & 3 & 8 \\1 & 4 & 9\end{array}\right]$

$B-5 A=$ $\left[\begin{array}{lll}7 & 3 & 8 \\1 & 4 & 9\end{array}\right]$ $-5\left[\begin{array}{lll}0 & 4 & 9 \\8 & 3 & 7\end{array}\right]$

$=\left[\begin{array}{lll}7 & 3 & 8 \\1 & 4 & 9\end{array}\right]$$-\left[\begin{array}{ccc}0 & 20 & 45 \\40 & 15 & 35\end{array}\right]$

  $=\left[\begin{array}{ccc}7-0 & 3-20 & 8-45 \\1-40 & 4-15 & 9-35\end{array}\right]$

   = $\left[\begin{array}{ccc}7 & -17 & -37 \\-39 & -11 & -26\end{array}\right]$

$B-5 A=$  $\left[\begin{array}{ccc}7 & -17 & -37 \\-39 & -11 & -26\end{array}\right]$
