00:00So this question to me, very simple, just look at the question and don't panic, so first of all we
00:07Multiplying a set, as you know, will go from first row into column, so for the first element, this
00:14fruit row into fruit
00:30What this becomes is Q, so Q will put CD into EG, so CE plus DG,
00:37What this becomes, CE plus DG is equal to Q,
00:40From CD into FH, that's CF plus DG, what this becomes, P, so the matrix comes in my par
00:49So, we have to find this much determinant. This becomes P square minus Q square, this much determinant. So this is the answer.
00:57will go, option number D,
