Listed following are several fictitious stars with their luminosities given in terms of the Sun’s luminosity () and their distances from Earth given in light-years (). Rank the stars based on how bright each would appear in the sky as seen from Earth, from brightest to dimmest. If two (or more) stars have the same brightness in the sky, show this equality by putting them next to each other

Shelby:100 L sun,10ly
Ferdinand: 400Lsun,20ly
Enzo 200 Lsun,20ly
Lotus:400 Lsun,40ly
Nismo: 100 Lsun,8ly


Can someone explain to me how to do this?
