Let A be a nonsingular n x n matrix, with n ≥ 2. Prove the following formula. ladj(A)| = |A|-1 Since A is nonsingular, we know that A. adj(A) = |AT|A B.O adj(A) = |A|AT C. adj(A) = |A¹|A D.O adj(A) = 0 E. O adj(A) = |A|A-1 -Select--- |adj(A)| = |AI|A-¹1 BO ladj(A)| = |A|-|A| C.O ladj(A)| = |A|^|A| DO ladj(A)| = |A|¹|A| E.O ladj(A)| = |A|A| To conclude, we apply ---Select--- --Select--- A is invertible A has an entire row consisting of zeros A is equal to its transpose the determinant of A is zero Taking the determinant of both sides of this equality and applying the property of a scalar multiple of a matrix gives which of the following?
