Consider A, B and C, all nxn matrices.
Show that:
1) det(A)=det(A^T)
2) if C was obtained from A by changing the i-th row (column) with
the j-th row (column). Show that det(C)=-det(A)
3) det(AB)=det(A)det(B)
4) Let C be a matrix obtained from A by multiplying a row by c ∈ F.
Show that det(B)=c · det(A)
True or False. Indicate whether the statement is true or false.
If false, explain in the space provided the statement why it is
