Question

sendo A e B : Faça as operações: a-b (transposta)​

Answer 1

$\mathsf{A}=\begin{pmatrix}-7&-3\\4&-8\\-1&-6\end{pmatrix}$

$\mathsf{B}=\begin{pmatrix}2&-5&3\\1&4&9\end{pmatrix}$

$\mathsf{B^T}= \begin{pmatrix}2&1\\-5&4\\3&9\end{pmatrix}$

$\mathsf{A-B^T}=\begin{pmatrix}-7&-3\\4&-8\\-1&-6\end{pmatrix}-\begin{pmatrix}2&1\\-5&4\\3&9\end{pmatrix} \\\mathsf{A-B^T} = \begin{pmatrix}-9&-4\\9&-12\\-4&-15\end{pmatrix}$
