Best ResponseYou've already chosen the best response.0But if you did that, how would the determinant be found? That makes no sense how that can be found if it is in the rows and columns like that. So in thousands, would the first be 10000,000?

Best ResponseYou've already chosen the best response.0Right, so what would that be? In thousands? Because that is what it is listed as in the problem copied

Best ResponseYou've already chosen the best response.0okay. so what I am going to do (just to make sure I understand the drawings) 1. 500*200, 500*15, 500*5 2. 600*30, 600*5, 600*2 Then add the results of 500*2 and 600*30 together, and so on? Is that correct?
