4. If $$ A=\left[\begin{array}{cccccc}0 & 0 & -3 & -2 & 0 & 5 \ -2 & 3 & 0 & 0 & 0 & 0 \ 0 & 0 & 0 & -2 & 0 & 0 \ 1 & -2 & 3 & 0 & 0 & 0 \ -2 & 8 & 3 & 6 & 2 & 7 \ 0 & 2 & 3 & 0 & 0 & 0\end{array}ight] $$ compute $$ \operatorname{det}(A), \quad(\operatorname{adj}(A))^{-1} \operatorname{and} \operatorname{det}(\operatorname{adj}(A)) $$.

Boyd Chandler · Accepted Answer

Determinant $$ \det(A) = -300 $$, ters adjoint matrisi $$ \operatorname{adj}(A)^{-1} = -\dfrac{1}{300} A $$, ve adjoint matrisinin determinantı $$ \det(\operatorname{adj}(A)) = -243{,}000{,}000{,}000 $$.
