Question

B[bij] 2x3, tal que bij= (${i}^{j}$)
​

Answer 1

Lembrando que "i" é a linha e "j" a coluna do elemento da matriz, temos:

$B~=~\left[\begin{array}{ccc}b_{11}&b_{12}&b_{13}\\b_{21}&b_{22}&b_{23}\end{array}\right]\\\\\\\\B~=~\left[\begin{array}{ccc}1^1&1^2&1^3\\2^1&2^2&2^3\end{array}\right]\\\\\\\\B~=~\left[\begin{array}{ccc}1&1&1\\2&4&8\end{array}\right]$
