Question

3. If A and B are two matrices of size 4 x 4 such that Det(A) = -3 and
Det(B) = 3/2, then Det((2.A)^-2(4B^3)^T) is:

Answer 1

Step-by-step explanation:

1st step is to substitute

(2.-3)-2 (4.3/2^3)

P.s the dots are used to represent multiplication.

Then use BODMAS.

which eventually becomes -6-2 (12/2^3)

-8^2

-4

I might not be correct, but at least I tried. Comment the correct answer below of am wrong.
