Solved Let B 0 1 1 1 0 1 1 1 0 And B Chegg Since the determinant of a product of matrices is the product of their determinants, we have: det (b^5) = (det (b))^5 now, we know that det (b) = 1, so: det (b^5) = ( 1)^5. We have, a= [ (1, 2, 1), ( 1, 1, 2), ( 2, 1, 1)] ∣a∣=1 (1 2)−2 (−1−4)−1 (1−2) =3 10 1=14 we know that, for a square matrix of order n, adj (adja)=∣a∣^ (n−2)a, if ∣a∣!=0 det (adj (adja))=∣∣a∣^ (n−2)a∣ det (adj (adja))= ( (∣a∣^ (n−2)))^n∣a∣ det (adj (adja))=∣a∣^ (n^2−2n 1) here, n=3 and ∣a∣=14. Wolfram|alpha is the perfect resource to use for computing determinants of matrices. it can also calculate matrix products, rank, nullity, row reduction, diagonalization, eigenvalues, eigenvectors and much more. use plain english or common mathematical syntax to enter your queries. For an invertible matrix a, adj (a) = det (a) * a⁻¹. the determinant of the adjugate is related to the determinant of the original matrix. we are given the matrix a = 1 1 0 2 0 1 α 1 2 and the condition det(adj(2a−at)⋅ adj(a−2at)) = 28. we need to find (det(a))2. at = 1 2 α 1 0 1 0 1 2.
