Question: The magnitudes (visual brightness), m 1 and m 2 , of two stars are related to their (actual) brightness's, b 1 and b 2 ,

The magnitudes (visual brightness), m₁ and m₂, of two stars are related to their (actual) brightness's, b₁ and b₂, by the equation m₁ − m₂ = 2.5 log₁₀ (b₂/b₁). Solve for b₂.
