Question

5)construa a matriz B=[Bij]2×2 tal que Bij=(i-j)³+5​

Answer 1

$B=\begin{vmatrix}b_{11}&b_{12}\\b_{21}&b_{22}\end{vmatrix}$

$\mathsf{b_{11}={(1-1)}^{3}+5=5}\\\mathsf{b_{12}={(1-2)}^{3}+5=4}\\\mathsf{a_{21}={(2-1)}^{3}+5=6}\\\mathsf{a_{22}={(2-2)}^{3}+5=5}$

$\huge\,B=\begin{vmatrix}5&4\\6&5\end{vmatrix}$
