Question

vc sabe fazer 1- determine a matriz C= (cij )1x3tal que cij=ji teremos qual matriz

Answer 1

$C=(c_{ij})_{1\times3}\qquad\qquad\qquad{c}_{ij}=j\cdot{i}\\\\\\C=\begin{bmatrix}c_{11}&c_{12}&c_{13}\end{bmatrix}\\\\\begin{matrix}c_{ij}=j\cdot{i}\end{matrix}$


$\begin{matrix}c_{11}=1\cdot1\\\\c_{11}=1\end{matrix}\end{matrix}\qquad\qquad\begin{matrix}c_{12}=2\cdot1\\\\c_{12}=2\end{matrix}\qquad\qquad\begin{matrix}c_{13}=3\cdot1\\\\c_{13}=3\end{matrix}$


$\boxed{C=\begin{bmatrix}1&2&3\end{bmatrix}}$
