A calculation about the energy evolution of the relativistic particles in galaxy clusters is presented. The heating of X-ray gas by radio gas in cluster PKS 0745-191 is derived through a combined analysis of Chandra data and VLA radio observations. It was found that the heating of X-ray gas by radio gas is not enough to supply the energy lose by the X-ray emission when the low energy cut-off in the power-law spectrum of the relativistic electrons is set to 0.001erg. Therefore further computing is made to study the heating of X-ray gas by radio gas with different low energy cut-off is computed and the low energy cut-off values.
