Let A=[[1,2,6,-1],[-10,2,6,0],[-4,0,-2,-6],[1,-3,-9,2]]. Compute the determinant of A. det(A)= (a) 0 (b) 1 (c) -1 (d) 2. Compute det(-3A^(2)). det(-3A^(2))= (a) 0 (b) 1 (c) -1 (d) 2. Suppose that B is an invertible matrix such that det(A^(2))=2. Compute det(B^(-1)). det(B^(-1))= (a) 0 (b) 1 (c) -1 (d) 2.
