If a is an n× n matrix, then det a = det at . verify this theorem for 2 × 2 matrices.

Verified

Step-by-step explanation:

Let A matrix be in the form of

Then det(A) = ad - bc

Matrix A transposed would be in the form of:

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

final answer is : )

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !
