Web8 apr. 2012 · adj(adjA)=[(detA)^(n-2)].A (n>=2) property of adjoints and determinants can be proved using two three equations. We know that inverse of A is equal to adjoint of A … WebCorrect option is C) Consider. A= ∣∣∣∣∣∣∣∣a000a000a∣∣∣∣∣∣∣∣. Firstly we find the determinant of A as shown below: ∣A∣=a[(a)(a)−(0)(0)]−0[(0)(a)−(0)(0)]+0[(0)(0)−(0)(a)] ∣A∣=a[a 2]−0+0. … Web8 apr. 2012 · We know that inverse of matrix is calculated using formula: Multiplying this equation by A, we can write as and and From above, we can say that det (A)I=A.adj (A) and det (A)I=adj (A).A From above equations, we can say that A.adj (A)=adj (A).A=det (A)I which is the desired result. dayspring father\\u0027s day ecards
