Combining Variations: Solve the problem using the relationship between brightness B, luminosity L, and distance d derived in Example 3. The proportionality constant is k = 0.080.
brightness of a Star: The luminosity of a star is L = 2.5 
W, and its distance from the earth is
d = 2.4 
m. How bright does the star appear on the earth?
