Surely,  for any  nxn-matrix  B  there are  nxn-matrices  K,  A  and  N  such that   B = KAN.

Simply take  A = B,  K = I  (the identity matrix),  N = I.

In your post,  you missed some important properties of matrices  A,  B,  K  and  N,  that make the problem  SPECIAL.

As it is worded in your post,  the statement is  TRIVIAL.

It is valid for any square  nxn-matrix  B,  independently of its determinant.

So, twice and thrice check with your source.

The term  "matrice"  in English is  "matrix".

Use  "matrix"  for single.

Use  "matrices"  for plural.
