Web24 feb. 2024 · (a) If det A = ± 1, then A -1 need not exist (b) If det A = ± 1, then A -1 exists but all entries are not necessarily integers. (c) If det A ≠ ± 1, then A -1 exists and all its entries are non-integers (d) If det A = ± 1, then A -1 exists and all its entries are integers. Answer Question 18. Web31 jul. 2024 · Then A = product of eigen values = 2 × × 3 × × 4 = 24. We know that if λ1, λ2 λ 1, λ 2 & λ3 λ 3 are eigen values of A then A λ1, A λ2 A λ 1, A λ 2 & A λ3 A λ 3 are eigen values of adjoint of matrix A. Therefore, 24 2, 24 3, 24 4 24 2, 24 3, 24 4 are eigen values of adj. A. ⇒ 12, 8 & 6 are eigen values of adj. A.
