If `A=[a_(i j)]` is a `3xx3` diagonal matrix such that `a_(11)=1` , `a_(22)=2` and `a_(33)=3` , then find `|A|` .

If A=[a_(i j)] is a 3xx3 scalar matrix such that a_(11)=2 , then write the value of |A| .

If A=[a_(i j)] is a 3xx3 scalar matrix such that a_(11)=2 , then write the value of |A| .

A=[a_(ij)]_(3xx3) is a square matrix so that a_(ij)=i^(2)-j^(2) then A is a

Let A=([a_(i j)])_(3x3) be a matrix such that a_(11)=a_(33)=2 and all the other elements a_(i j)=1 A^(-1)= (a) A^2+5A-I (b) A^2-5A+5I (c) A^2+5A-5I (d) A^2+5A+5I

Let A=([a_(i j)])_(3x3) be a matrix such that a_(11)=a_(33)=2 and all the other elements a_(i j)=1 . A^(-1)= A^2+5A-I (b) A^2-5A+5I A^2+5A-5I (d) A^2+5A+5I

if a = 3 and a_(7) = 33 , then a_(11) is

Let A=[a_(ij)]_(3xx3) be a scalar matrix and a_(11)+a_(22)+a_(33)=15 then write matrix A.

Let A=[a_(ij)]_(3xx3) be a scalar matrix and a_(11)+a_(22)+a_(33)=15 then write matrix A.

If matrix A=[a_(ij)]_(3xx2) and a_(ij)=(3i-2j)^(2) , then find matrix A.

Let A=[a_(ij)]_(3xx3) be a matrix such that A.A^(T)=4I and a_(ij)+2c_(ij)=0 where c_(ij) is the cofactor of a_(ij) AAi & j , I is the unit matrix of order 3 and A^(T) is the transpose of the matrix A If |(a_(11)+4,a_(12), a_(3)),(a_(21),a_(22)+4,a_(24)),(a_(31),a_(32),a_(33)+4)|+5lamda|(a_(11)+1,a_(12),a_(13)),(a_(21),a_(22)+1,a_(23)),(a_(31),a_(32),a_(33)+1)|=0 then lamda=a/b where a and b are coprime positive integers then the value of a+b is______
