So i have these two matrices where all i know is that they are 6 by 6 and I have their determinants, how would I work out the above? I know I need to use, or can use, the properties of determinants but I feel like there might be more to it than it being as simple as multiplying by -1 or 3. Thanks

Use some of these properties of the determinant to help you out.

  • $\begingroup$ Yes, and a combination of properties 2, 3, and 4 for the third problem. $\endgroup$
