Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

no it will never change by applying column or row operations.
what other properties don't change after row transformation?
and what other properties of a matrix do change after row operation?
only matrix will change and nothing else
I am asking for rank, eigenvalues, nullity, etc
they will be same
eigenvalues will not be the same.
oh sorry yes Eigen values may get change . This can be observed in this way that determinant may get change and trace may get change which implies their is some change in Eigen values.
