Question

sejamA=( 2 3 4-1 0 2) eB=(-2 0 7-1 8 5) determine ( A+ B)t​

Answer 1

$A=\begin{bmatrix}2&3&4&-1&0&2\end{bmatrix}$

$B=\begin{bmatrix}-2&0&7&-1&8&5\end{bmatrix}$

$A+B\\=\begin{bmatrix}2&3&4&-1&0&2\end{bmatrix}\\+\begin{bmatrix}-2&0&7&-1&8&5\end{bmatrix}\\=\begin{bmatrix}0&3&11&-2&8&7\end{bmatrix}$

${(A+B)}^{T}=\begin{bmatrix}0\\3\\11\\-2\\8\\7\end{bmatrix}\color{blue}{\checkmark}$
