Construct a matrix `A=[a_(ij)]_(3xx2)`whose elements `a_(ij)` are given by: `a_(ij)=(frac((i+j)^3)(5))`

Construct a matrix A=[a_(ij)]_(3xx2) whose elements à_(ij) are given by: a(ij)=(frac((i-j)^2)(5-i))

Construct a matrix A=[a_(ij)]_(3xx2) whose elements à_(ij) are given by: a(ij)=i-3j

Construct a matrix of order 2x2,where elements are given by a_(ij)=(frac((i+j)^2)(2))

Construct the matrix A=[a_(ij)]_(3xx3) where a_(ij)=i-j . State whether A is symmetric or skew symmetric.
