Question

escreva a matriz A=(a i j ) 2×2,tal que aij=ij

Answer 1

matriz 2x2
[11 12]
[21 22]
A11=1+1=2
A12=1+2=3
A21=2+1=3
A22=2+2=4

Answer 2

$\textsf{Resolu\c{c}\~ao~da~quest\~ao,~veja~como~fica}:\\\\\\\ \textsf{Desenvolver~a~matriz~do~tipo~aij~2 x 2~tal~que~aij=ij}:\\\\\\\ \begin{pmatrix}a_{11} &a_{12} \\a_{21} &a_{22} \end{pmatrix}\\\\\\ \textsf{Se~aij = ij,~teremos~que}:\\\\\\ a_{11} = 1~\cdot~1 =\ \textgreater \ ~a_{11}= 1\\\\\ a_{12} = 1~\cdot~2=\ \textgreater \ ~a_{12} = 2\\\\\\ a_{21} = 2~\cdot~1=\ \textgreater \ ~a_{21} = 2\\\\ a_{22} = 2~\cdot~2=\ \textgreater \ a_{22} = 4\\\\\\\ \textsf{Montando-se~a~matriz~teremos~que}:\\\\\\\ {\begin{pmatrix} 1&2 \\ 2&4 \end{pmatrix}$
