If A is a square matrix of order 3x3 and |A|=3 then find the value of |A x adjA|.

Ms. Priyanka Kediaor anyone else please do not redirect me to this page:

This is not the same answer that I require. I just want a direct answer.

Since A is 3 x 3, taking determinants of both sides yields 
|A * adj(A)| = |A|3'
=33=27
