7.(6) Let A be a square matrix of size 4x4 and if det(A) = -1. Find det(3A) and the rank of A.
Suppose A is a square matrix such that det A4 invertible. 0. Prove that A is not Suppose that A is a square matrix such that det A" invertible and that it must have determinant 1. 1. Prove that A is Matrices whose determinant is 1 are part of a group (not just the english word, a special math term, ask if you want the deets) called the Special Linear Group, denoted SL(n) + Drag and drop your files or...
