Question

deetermine a matriz de.e=[eij] 5.1 em que eij = 4i(i ao quadrado ) +3j​

Answer 1

$Temos\ que\ a\ matriz\ E_{5x1} =\ e_{ij} \ dada\ da\ seguinte\ maneira:\\\\E = \left[\begin{array}{ccc}e_{11}\\e_{21}\\e_{31}\\e_{41}\\e_{51} \end{array}\right] \\\\Basta\ fazermos\ as\ contas\ onde\ e_{ij} = 4i^{2} + 3j\ ,\ sendo\ assim,\ teremos:\\\\E = \left[\begin{array}{ccc}4*1^{2}+3*1 \\4*2^{2}+3*1\\4*3^{2}+3*1\\4*4^{2}+3*1\\4*5^{2}+3*1 \end{array}\right] = \left[\begin{array}{ccc}4*1+3\\4*4+3\\4*9+3\\4*16+3\\4*25+3 \end{array}\right]$$E = \left[\begin{array}{ccc}7\\19\\39\\67\\103 \end{array}\right]$
