`I fA=[a_(i j)]_(2xx2)` such that `a_(i j)=i-j+3` ,then find A.

If A=[a_(i j)] is a 2xx2 matrix such that a_(i j)=i+2j , write A .

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

If A=[a_(ij)]_(mxxn) and a_(ij)=i(i+j) then find trace of A.

If A=|a_(ij)]_(2 xx 2) where a_(ij) = i-j then A =………….

if A=[a_(ij)]_(3xx3) such that a_(ij)=2 , i=j and a_(ij)=0 , i!=j then 1+log_(1/2) (|A|^(|adjA|))

If A=[a_(i j)] is a square matrix such that a_(i j)=i^2-j^2 , then write whether A is symmetric or skew-symmetric.

If matrix A=([a_(i j)])_(2xx2) , where a_(i j)={1,\ if\ i!=j0,\ if\ i=j , then A^2 is equal to I (b) A (c) O (d) I

If matrix A = [a_(i j)]_(2 xx 2) , where a_(i j) = {("1 if",i ne j),("0 if",i = j):} then A^(2) is equal to

If matrix A=[a_(ij)]_(2xx2) where a_(ij)={{:(2,i ne j),(0, i=j):} then write the matrix A.
