यदि A = [{3, -5}, {-1, 2}] तो adjoint A =

Question

यदि \(A=\left[\begin{array}{rr}3 & -5 \\ -1 & 2\end{array}\right]\) तो adjoint \(A=\)

(A) \(\left[\begin{array}{ll}2 & 5 \\ 1 & 3\end{array}\right]\)

(B) \(\left[\begin{array}{ll}2 & 3 \\ 1 & 5\end{array}\right]\)

(C) \(\left[\begin{array}{ll}1 & 3 \\ 2 & 5\end{array}\right]\)

(D) \(\left[\begin{array}{ll}2 & 1 \\ 5 & 3\end{array}\right]\)

Answer 1

सही विकल्प है (A) \(\left[\begin{array}{ll}2 & 5 \\ 1 & 3\end{array}\right]\) 

\(A=\left[\begin{array}{rr}3 & -5 \\ -1 & 2\end{array}\right]\)

\(adj \ A = \left[\begin{array}{ll}2 & 5 \\ 1 & 3\end{array}\right]\)
