Let a matrix `A=[[2,3],[1,2]]` then `A^(-1)` will be

" For a given square matrix "A" ,if there exists a matrix "B" such that "AB=BA= I "then "B" is called inverse of "A" Every non - singular square matrix possesses inverse and it exists if" |A|!=0,A^(-1)=(adj(A))/(det(A))rArr adjA=|A|(A^(-1))"Let a matrix "quad A=[[2,3],[1,2]]" then" A^(-1)" will be "

Let matrix A=[[3,2],[1,1]] satisfies the equation A^2+aA+bI=0 then the value of |a+b| =

find matrix 2[[2,3-1,5]]+[[1,23,4]]

The inverse of matrix [[2, -3], [-1, 2]] is

Let the matrix A=[(1,2,3),(0, 1,2),(0,0,1)] and BA=A where B represent 3xx3 order matrix. If the total number of 1 in matrix A^(-1) and matrix B are p and q respectively. Then the value of p+q is equal to

Let A=[(-1,2,-3),(-2,0,3),(3,-3,1)] be a matrix, then |A|adj(A^(-1)) is equal to

Let A=[(-1, 2, -3),(-2,0,3),(3,-3, 1)] be a matrix, then |a| adj(A^(-1)) is equal to

If A=[[2,-2,-4],[-1,3,4],[1,-2,-3]] then A is 1) an idempotent matrix 2) nilpotent matrix 3) involutary 4) orthogonal matrix

If A=[[2,-2,-4],[-1,3,4],[1,-2,-3]] then A is 1) an idempotent matrix 2) nilpotent matrix 3) involutary 4) orthogonal matrix
