Vedclass · Answer

(C) Given $A = \begin{bmatrix} 1 \ 2 \ 3 \end{bmatrix}$.The transpose of matrix $A$,denoted by $A'$,is obtained by interchanging its rows and columns:$A' = \begin{bmatrix} 1 & 2 & 3 \end{bmatrix}$.Now,calculate the product $AA'$:$AA' = \begin{bmatrix} 1 \ 2 \ 3 \end{bmatrix} \begin{bmatrix} 1 & 2 & 3 \end{bmatrix} = \begin{bmatrix} 1 	imes 1 & 1 	imes 2 & 1 	imes 3 \ 2 	imes 1 & 2 	imes 2 & 2 	imes 3 \ 3 	imes 1 & 3 	imes 2 & 3 	imes 3 \end{bmatrix} = \begin{bmatrix} 1 & 2 & 3 \ 2 & 4 & 6 \ 3 & 6 & 9 \end{bmatrix}$.Thus,the correct option is $C$.

If $A = \begin{bmatrix} 1 \\ 2 \\ 3 \end{bmatrix}$,then $AA' = $
