Q6 of 45 Page 1

If Aij is the cofactor of the element aij of the determinant then write the value of a32. A32.

Given determinant is


a32 represents the element of 3rd row and 2nd column of the given determinant.


∴ a32 = 5


Whereas A32 represents the element of co-factor matrix of the given determinant.


A32 is as-


A32 = (-1)3+2 = -(8-30) = 22


∴ A32 = 22


∴ a32.A32 = 5×22 = 110
