Alo! I kinda need some assistance to proof this:
"Show that adj(adj A) = |A|^(n-2). A, if A is a (n x n) square matrix and |A| is not equal to zero"
NOTE: 1) adj(A) = adjugate of matrix A,
2) |A| = determinant of A,
3) ^ = power
I've tried to work around the equation using the formula: A^-1 = |A|^-1. adj(A), BUT doesn't seem to work at all. Sooo HELP!..and thanks in advance .
