If `A=[[2,3],[5,-2]]`,then `A^(-1)` is:

If A=[(2,3),(5,-2)] then 9A^-1 is equal to (A) A\' (B) 2A (C) 1/2 A (D) A

If A=[{:(2,3),(5,-2):}] , write A^(-1) in terms of A.

If A=[[-1,5],[-3,2]] , then adj A= (A) [[2,3],[-5,-1]] (B) [[1,-5],[3,-2]] (C) [[2,-5],[3,-1]] ,(D) [[-2,5],[-3,1]]

Assertion (A) : If A=[{:(2,3),(5,-2):}] and A^(-1)=kA , then k=(1)/(9) Reason (R ) : |A^(-1)|=(1)/(|A|)

Find the inverse of each of the matrices given below : If A=[(2,3),(5,-2)], " show that " A^(-1)=1/19A.

If A=[(2, 3),(5,-2)] be such that A^(-1)=k\ A , then find the value of k .

If A=[(2;3);(5;-2)]; find A^(-1)

If A=[[1,2,-3] , [5,0,2] , [1,-1,1]] and B=[[3,-1,2] , [4,2,5] , [2,0,3]] then find matrix C such that A+2C=B

If A= [[2,3,5],[1,2,1],[0,1,7]] and A^(3)-lambda A^(2)+28A-10=0 , then the value of lambda is

If A=[[0, 1,2],[1,2,3],[3,a,1]]and A^(-1)[[1//2,-1//2,1//2],[-4,3,b],[5//2,-3//2,1//2]] then
