Question

If ∆=$\left\begin{vmatrix}a_{11} &a_{12}&a_{13}\\a_{21}&a_{22}&a_{23}\\a_{31}&a_{32}&a_{33}\end{vmatrix}\right$and Aij is Cofactors of aij, then value of Δ is given by
A. a11 A31+ a12 A32 + a13 A33
B. a11 A11+ a12 A21 + a13 A31
C. a21 A11+ a22 A12 + a23 A13
D. a11 A11+ a21 A21 + a31 A31

Answer 1

2^{23}, $\textstyle n_{i-1}$, n_{i-1}. $a^{i +1}_3$, a^{i+1}_3, $x^{3^2}$, x^{3^2}. $2^{a_i}$, 2^{a_i}, $2^a_i$, 2^a_i ...
