Which of the following is not correct in...

Which of the following is not correct in a given determinant of `A ,` where `A=([a_(i j)])_(3x3)`

A. Order of minor is less than order of the det(A)
B. Minor of an element can never be equal to cofactor of the same element
C. Value of a determinant is obtained by multiplying elements of a row or column by corresponding cofactors
D. Order of minors and cofactors of elements of A is same

Text Solution

Verified by Experts

`A= [a_(ij) ]_(3xx3)`
minor=`2 xx2`
`[(1,0,0),(0,1,0),(0,0,1)] `
`c_(11) = 1`
minor can be equal to cofactor
