## Homework Statement

For main sequence stars, the mass–luminosity relation can be approximated by L[itex]\propto[/itex]M[itex]^{3.5}[/itex]

f) If luminosity and mass are both measured in solar units, what is the constant of

proportionality? {2}

I know that the luminosity value of the sun is 4x10[itex]^{26}[/itex]W and

M = 2x10[itex]^{30}[/itex] kg
