this is the rule of maths when one side is same than other side is also same
in this equations "E" is Same
but "mc²" or "hv" hav not relation

What you seem to be saying is that mc²=E=hν doesn't have a relationship. But it does. If you have a know quantity of matter and want to find what frequency of light would have the same energy, simply put mc²/h=ν. Or go from a frequency to mass. Those two equations are what allows physicist to express mass in terms of eV or electronvolts.

They do in certain circumstances, for instance in nuclear physics; a reaction may cause a gamma ray (i.e. photon) to be emitted, with energy given by E = hν. This translates into a loss of binding mass in the nucleon, and the amount of mass lost is determined by mc² = hν and thus m = hν/c².

E = MC2
Energy = Mass X Speed of Light Squared.
See the theory of relativity on wikipedia or Einstien.

e=mc2 is the relation for energy when a matter gives out energy. while e=hv is relation of energy for a wave.
