Question

B(bij)2x2=bij=i2+2j-1

Answer 1

Matriz 2x2, ou seja, duas linhas e duas colunas, sendo que bji=i2+2j-1: | b11 b12| |b21 b22| __________________________ B11= 1.2+2.1-1= 4-1=3 | B12= 1.2+2.2-1= 6-1=5 | B21= 2.2+2.1-1= 6-1=5 | B22= 2.2+2.2-1= 8-1=7 | _____________________________ Montando a matriz B : | 3 5 | | 5 7 |

Answer 2

$B=\left[\begin{matrix} b_{11}&b_{12}\\ b_{21}&b_{22}\\ \end{matrix}\right]= \left[\begin{matrix} 1^2+2(1)-1&1^2+2(2)-1\\ 2^2+2(1)-1&2^2+2(2)-1\\ \end{matrix}\right] \\\\ \\\boxed{B= \left[\begin{matrix} 2&4\\ 5&7\\ \end{matrix}\right]}$
