Question

If A = $open square brackets table row 1 2 row cell negative 1 end cell 2 end table close square brackets$ and B = $open square brackets table row 3 4 row 2 cell negative 2 end cell end table close square brackets$ , then (AB)^T is-

$[\begin{matrix} 11 & - 2 \\ 5 & - 6 \end{matrix}]$
$[\begin{matrix} 11 & 5 \\ - 2 & - 6 \end{matrix}]$
$[\begin{matrix} 7 & 1 \\ 0 & - 8 \end{matrix}]$
$[\begin{matrix} 7 & 0 \\ 1 & - 8 \end{matrix}]$

The correct answer is: $open square brackets table row 7 1 row 0 cell negative 8 end cell end table close square brackets$

To find the value of $open parentheses A B close parentheses to the power of T$ .
Given, A = $open square brackets table row 1 2 row cell negative 1 end cell 2 end table close square brackets$ and B = $open square brackets table row 3 4 row 2 cell negative 2 end cell end table close square brackets$ .
(AB) = A x B = $open square brackets table row 1 2 row cell negative 1 end cell 2 end table close square brackets$ x $open square brackets table row 3 4 row 2 cell negative 2 end cell end table close square brackets$
(AB) = $open square brackets table row 7 0 row 1 cell negative 8 end cell end table close square brackets$ .
$open parentheses A B close parentheses to the power of T$ = $open square brackets table row 7 1 row 0 cell negative 8 end cell end table close square brackets$

Therefore, by matrix multiplication, $open parentheses A B close parentheses to the power of T$ = $open square brackets table row 7 1 row 0 cell negative 8 end cell end table close square brackets$ .
