Question

Escreva a matriz A=(aij)3×4 na qual aij=3i + 2j.

Answer 1

$A_{3,4} = \left[\begin{array}{cccc}a_{1,1}&a_{1,2}&a_{1,3}&a_{1,4}\\a_{2,1}&a_{2,2}&a_{2,3}&a_{2,4}\\a_{3,1}&a_{3,2}&a_{3,3}&a_{3,4}\end{array}\right]\\ A_{3,4} = \left[\begin{array}{cccc}3.1+2.1&3.1+2.2&3.1+2.3&3.1+2.4}\\3.2+2.1&3.2+2.2}&3.2+2.3&3.2+2.4}\\3.3+2.1&3.3+2.2&3.3+2.3&3.3+2.4}\end{array}\right]\\ A_{3,4} = \left[\begin{array}{cccc}5&7&9&11}\\8&10}&12&14}\\11&13&15&17}\end{array}\right]$
