Question

Escrevendo a matriz B=(bij)1x3, tal que bij = 2i +j2.

Answer 1

Matriz 

$\left[\begin{array}{ccc}b11&b12&b13\\\\\end{array}\right] 1x3$

obtendo a matriz 

bij=2i+j2
b11=2.1+2.1= 2+2 =4 
b12=2.1+2.2 =2+4 =6
b13=2.1+3.2 =2+6 =8 

Logo a matriz será:

$\left[\begin{array}{ccc}4&6&8\\\\\end{array}\right]$

Espero ter ajudado!
