Question

Construa a matriz real quadrada A de ordem 3, definida por:

Answer 1

Explicação passo a passo:

$\left[\begin{array}{ccc}a_{11}&a_{12}&a_{13}\\a_{21}&a_{22}&a_{23}\\a_{31}&a_{32}&a_{33}\end{array}\right] =\left[\begin{array}{ccc}1&8&16\\4&3&32\\9&8&7\end{array}\right]$

$a_{11}=1^2-1+1=\not1-\not1+1=1\\ \\ a_{12}=2^{1+2}=2^3=8\\ \\ a_{13}=2^{1+3}=2^4=16\\ \\ \\ a_{21}=2^2-\not1+\not1=4\\ \\ a_{22}=2^2-2+1=4-1=3\\ \\ a_{23}=2^{2+3}=2^5=32$

$a_{31}=3^2-\not1+\not1=9\\ \\ a_{32}=3^2-2+1=9-1=8\\ \\ a_{33}=3^2-3+1=9-2=7$
