adj AB -(adj B)(adj A) =

adj AB -(adj B) (adj A) =

If A=[[3,1],[2,5]]B=[[1,2],[2,3]] verify adj (AB) = (adj B) (adj A)

For two non-singular matrices A&B, show that adj (AB)=adj(AB)=(adjB)(adjA)

If A and B are any two square matrices of the same order then (A) (AB)^T=A^TB^T (B) (AB)^T=B^TA^T (C) Adj(AB)=adj(A)adj(B) (D) AB=0rarrA=0 or B=0

If A and B are any two square matrices of the same order then (A) (AB)^T=A^TB^T (B) (AB)^T=B^TA^T (C) Adj(AB)=adj(A)adj(B) (D) AB=0rarrA=0 or B=0

If A is any 4- square matrix then which of the following is true ? (a) |adj A| = |A | ^(2) (b) |ad A | = |A | ^(3) (c ) |adj A | = |A| ^(4)

ABC is a right triangle right-angled at A and AD perp BC. Then,(BD)/(DC)=((AB)/(AC))^(2) (b) (AB)/(AC) (c) ((AB)/(AD))^(2) (d) (AB)/(AD)

adj AB -(adj B)(adj A) = ....a) adjA−adjB b) 1 c) 0 d) none of these

In a triangle ABC, right angled at A, on the leg AC as diameter,a semicircle is described. If a chord joins A with the point of intersection D of the hypotenuse and the semicircle,then the length of AC is equal to (AB.AD)/(sqrt(AB^(2)+AD^(2))) (b) (AB.AD)/(AB+AD)sqrt(AB.AD)(d)(AB.AD)/(sqrt(AB^(2)-AD^(2))) (b)
