Thanks for this. I am terribly late but can you refer me to some time of source or exercises where this is better explained,because I spent half an hour blidingly searching
Nothing specific that I know of, but any halfway decent linear algebra textbook should cover this. I'm sure there are many websites out there as well that discuss it.
Answer is :5 40
|2A| = 2^n * |A|, where n is the number of rows (or, equivalently, columns) of A.
you might find this set of examples useful.
???
C'mon! The least you could do is define A^T and 2A in the problem!

I was confused thinking |A| was some matrix norm. It's determinant...
I think my answer is correct. Why wa is returned ...
Determinant of A is 5 for both A^T and 2A
Sorry for the late reply but you might find this set of examples useful.
They are NOT useful, because NOWHERE do I find A^T or 2A defined!
