A star has a mass that is 3.5 times that of the Sun. Assuming that it's on the main sequence, how many solar luminosities is it?

In astrophysics, the mass–luminosity relation is an equation giving the relationship between a star's mass and its luminosity, first noted by Jakob Karl Ernst Halm.[1] The relationship is represented by the equation:

L

{\frac {L}{L_{{\odot =\left({\frac {M}{M_{{\odot \right)^{a}
where L⊙ and M⊙ are the luminosity and mass of the Sun and 1
