Let m (t) = cos [ (4^{_$\pi$ $\times$} 10³) t] be the message signal and c(t) = 5 cos[(2^{_$\pi$ $\times$} 10⁶)t] be the carrier. c(t) and m(t) are used to generate an AM signal. The modulation index of the generated AM signal is 0.5. Then the quantity ^{$\dfrac{Total sideband power}{Carrier power}$} is
