Suppose A is an n times n matrix with the property that AAT = In. Show that det A = plusminus 1. Find the determinant by row reduction to echelon form. Is the corresponding matrix invertible? Suppose Find the value of .Let A, B be 4 times 4 matrices with det A = -1 and det B = 2. Compute the determinant of the following matrices: AB, B5, 2A, AT A, B-1 AB
