If `a_j=0(i!=j)anda_(i j)=4(i=j)`,,then the matrix `A =[a_(i j)]_(n xx n)` is a matrix

If the elements of a matrix A of order 2 xx 3 are defined as a_(ij) = {{:(i + j , i =j),(i-j,i nej):} then the matrix A^(T) is :

Statement 1: If A=([a_(i j)])_(nxxn) is such that ( a )_(i j)=a_(j i),AAi ,ja n dA^2=O , then matrix A null matrix. Statement 2: |A|=0.

Construct 3xx4 matrix A=[a_(aj)] whose elements are: a_(ij)=i.j

Construct 3xx4 matrix A=[a_(aj)] whose elements are: a_(ij)=i/j

Construct 3xx4 matrix A=[a_(aj)] whose elements are: a_(ij)=i.j

Construct 3xx4 matrix A=[a_(aj)] whose elements are: a_(ij)=i/j

" In a square matrix "A=[a_(ij)]" ,if "i>j" and "a_(ij)=0" then that matrix 'A' is an "

"In a square matrix "A=a_(ij)" if i>j then "a_(ij)=0" then the Matrix A is"

A square matrix A=[a_(ij)] in which a_(ij)=0 for i!=j and [a]_(ij)=k (constant) for i=j is called a (A) unit matrix (B) scalar matrix (C) null matrix (D) diagonal matrix

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