easy

$A=\left[\begin{array}{ll}2 & 4 \\ 3 & 2\end{array}\right], B=\left[\begin{array}{cc}1 & 3 \\ -2 & 5\end{array}\right], C=\left[\begin{array}{cc}-2 & 5 \\ 3 & 4\end{array}\right]$ હોય, તો $A-B$ મેળવો

A

$\left[ {\begin{array}{*{20}{c}} 1&1 \\ 5&{ - 3} \end{array}} \right]$

B

$\left[ {\begin{array}{*{20}{c}} 1&1 \\ 5&{ - 3} \end{array}} \right]$

C

$\left[ {\begin{array}{*{20}{c}} 1&1 \\ 5&{ - 3} \end{array}} \right]$

D

$\left[ {\begin{array}{*{20}{c}} 1&1 \\ 5&{ - 3} \end{array}} \right]$

Solution

$A – B = \left[ {\begin{array}{*{20}{l}}
2&4 \\
3&2
\end{array}} \right] – \left[ {\begin{array}{*{20}{c}}
1&3 \\
{ – 2}&5
\end{array}} \right]$

$ = \left[ {\begin{array}{*{20}{c}}
{2 – 1}&{4 – 3} \\
{3 – ( – 2)}&{2 – 5}
\end{array}} \right]$

$ = \left[ {\begin{array}{*{20}{c}}
1&1 \\
5&{ – 3}
\end{array}} \right]$
