Question

determine a matriz em q c=[cij]2.3 em q cij = 2i+j ​

Answer 1

$Temos\ que\ a\ matriz\ C_{2x3} =\ c_{ij} \ dada\ da\ seguinte\ maneira:\\\\C = \left[\begin{array}{ccc}c_{11} &c_{12} &c_{13}\\c_{21} &c_{22} &c_{23}\end{array}\right] \\\\Basta\ fazermos\ as\ contas\ onde\ c_{ij} = 2i + j, sendo\ assim,\ teremos:\\\\C = \left[\begin{array}{ccc}2.1 + 1 &2.1 + 2&2.1+3 \\2.2 + 1 & 2.2 + 2&2.2+3 \end{array}\right] = \left[\begin{array}{ccc}3 &4&5 \\5 & 6&7 \end{array}\right]$
