Question

matriz quadrada de ordem 2, sendo aij= 2i- j:
 

Answer 1

Hola!!!!!!!!!!!!!!!!!

[ A11   A12 ] 
[ A21   A32 ]

Ok, então vamos à formula:
 Aij= 2i-j -------- A11 = 2x1-1=2-1=   1
Aij= 2i-j----------A12=  2x1-2=2-2=   0
Aij= 2i-j----------A21=2x2-1=4-1=     3
Aij=2i-j-----------A22=2x2-2=4-2=     2

[ 1  0 ]
[3   2 ]

 

Answer 2

Bom Dia!

Matriz:

$\begin{bmatrix}a11&a12\\a21&a22\\\end{bmatrix}$

$\mathrm{a11}\Rightarrow\mathrm{2\times1}-\mathrm{1}\Rightarrow\mathrm{2-1}=\boxed{\boxed{1}}</p><p>$

$\mathrm{a12}\Rightarrow\mathrm{2\times1}-\mathrm{2}\Rightarrow\mathrm{2-2}=\boxed{\boxed{0}}</p><p>$

$\mathrm{a21}\Rightarrow\mathrm{2\times2}+\mathrm{1}\Rightarrow\mathrm{4-1}=\boxed{\boxed{3}}</p><p>$

$\mathrm{a22}\Rightarrow\mathrm{2\times2}+\mathrm{2}\Rightarrow\mathrm{4-2}=\boxed{\boxed{2}}$

Matriz Resposta;

$\begin{bmatrix}1&0\\3&2\\\end{bmatrix}$
