I will show you some of the questions below but I am not looking for straight answers. I would like some pointers on how to go about solving these where to get help.

**Introduction**

Show if the folowing statements are true or false for 2 x 2 matrices.

1)

det(AB) = det(A)det(B)

2)

det(A^-1)= 1(over)det(A)

3)

det(A^T)=det(A)

Any advice would be greatly appreciated as this is due in one week and I have no clue how to go about this?

Thanks..
