Answer:

Verified

Step-by-step explanation:

Let A matrix be in the form of

[tex]\left[\begin{array}{cc}a&b\\c&d\end{array}\right][/tex]

Then det(A) = ad - bc

Matrix A transposed would be in the form of:

[tex]\left[\begin{array}{cc}a&c\\b&d\end{array}\right][/tex]

Where we can also calculate its determinant:

det(AT) = ad - bc = det(A)

So the determinant of the nxn matrix is the same as its transposed version for 2x2 matrices
