    Find determinant

    det(2A^8 B^{-1})

    I tried to break it up but I'm not sure where the 2 goes.

    det(2A^8) det(B^{-1}) ?




    Any help is appreciated!

    <br />
\det(2A^{8}B^{-1})=<br />
2^{3}\det(A^{8})\det(B^{-1})=<br />
8\frac{\det(A)^{8}}{\det(B)}=<br />
8\frac{ (-1)^{8}}{-2} = -4<br />
