det(A) =

det(A), A is a

if A has a row of zeros or a column of zeros then the det(A) = 1

if A is a square matrix then det(A) =det(A)T

In matrix B the first row of A was multiplied by k then

In the matrix B the first and second rows of A were interchanged

in the matrix B a multiple of the second row of A was added to the first row
