Question

How to prove that det|A|=det|AT|
AT=transposed matrix

Answer 1

Take any general 3X3 matrix and find its determinant...

Again take the transpose of the same matrix and find its determinant..

Both will come same...

Answer 2

proof by example?

Answer 3

Taking general example like taking variable like a b c etc..

Answer 4

or maybe prove tht det|A| doesn't change wqhen u change the places of two rows or columns
