Math Help - What is the determinant?

1. What is the determinant?

Suppose C and D and 5x5 matrices and det(C)=5, det(D)=6. Compute the determinant of the matrix 3C^T (4CD)^-1 C^2. Justify your answer by stating explicitly which calculation rules for the determinant you use.

2. Re: What is the determinant?

this is just some basic properties of the determinant which I'm sure are covered in your book.
