How Do You Calculate the Determinant of Complex Matrix Expressions?

[~Sam~]

Homework Statement

Suppose A is a 33 matrix such that det(A)=15.

Then det[A3((adj(A))−1)2]= and det[5A−1(adj(A))]

-1=inverse

Homework Equations

I know the properties of determinants and inverses

The Attempt at a Solution

Problem simplifying to get a number.

If you know the properties of determinants and inverses, can't you at least explain what the problem you are having is?
