Let `Ma n dN` be two `3xx3` matrices such that `M N=N Mdot` Further, if `M!=N^2a n dM^2=N^4,` then Determinant of `(M^2+M N^2)` is 0 There is a `3xx3` non-zeero matrix `U` such tht `(M^2+M N^2)U` is the zero matrix Determinant of `(M^2+M N^2)geq1` For a `3xx3` matrix `U ,if(M^2+M N^2)U` equal the zero mattix then `U` is the zero matrix
