Pt=pc (1=ma^2/2)
this total power has collaboration in career and sidebands as there are two side-bands.
So power should be pcma^2/4.

Yes @Raisul,
But that is the TOTAL power of the sidebands. Since the problems say that the system is SSBSC, we need the power for a single sideband only. That's why we divide it by 2.

Isn't power in sidebands is equal to (m^2*Pc)/2?
