::<math>m_{\mathrm{rel}} = \frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}}\,\, ? </math> Are you saying that the speed of light does not belong in either equation, and that the "c" should be something else? There are a number of equations in Einstein's Special Theory besides E=mc<sup>2</sup> and they hold together as far as they go. Everyone agrees that a general theory of relativity has not been developed, but the ideas of mass energy equivalence and relativistic mass fit the data. The designers of nuclear reactors and satellite systems use these equations with success.
