Question

construa a matrizB =[bij]2x2 , tal que bij= (i+j)² 

Answer 1

Matriz 2x2:

{ a11  b12 }    substituindo os valores temos:  { 4   9  }
{ a21  b22 }                                                  { 9  16 }  



bij=(i+j)²

a11=(1+1)²=(2)²=4
a12=(1+2)²= (3)²=9
a21= (2+1)² = (3)²=9
a22= (2+2)² = (4)² = 16

Answer 2

$B= \left[\begin{array}{ccc}b_{11}&b_{12}\\b_{21}&b_{22}\end{array}\right] \\ \\ B= \left[\begin{array}{ccc}(1+1)^2&(1+2)^2\\(2+1)^2&(2+2)^2\end{array}\right] \\ \\ B= \left[\begin{array}{ccc}4&9\\9&16\end{array}\right]$
