1.	Write dobun the minors of \( -2 \) and 4 in\[\left\|\begin{array}{rrr}2 & 1 & 1 \\1 & -2 & -3 \\3 & 2 & 4\end{array}\right\|\]
Answer» Minor of element -2 or a₂₂ in matrix is M₂₂ = \(\begin{vmatrix}2&1\\3&4\end{vmatrix}\) = 8 - 3 = 5 Minor of element 4 or a₃₃ in given matrix is M₃₃ = \(\begin{vmatrix}2&1\\1&-2\end{vmatrix}\) = -4 - 1 = -5.

Write dobun the minors of \( -2 \) and 4 in\[\left|\begin{array}{rrr}2 & 1 & 1 \\1 & -2 & -3 \\3 & 2 & 4\end{array}\right|\]

Answer»

Minor of element -2 or a₂₂ in matrix is

M₂₂ = \(\begin{vmatrix}2&1\\3&4\end{vmatrix}\) = 8 - 3 = 5

Minor of element 4 or a₃₃ in given matrix is

M₃₃ = \(\begin{vmatrix}2&1\\1&-2\end{vmatrix}\) = -4 - 1 = -5.
