Question

The ratio of brightness of two stars can be determined by a constant of 2.512 raised to the power of the magnitude difference. The formula is b₁/b₂ = 2.512^(m2 - m1) where b₁ and b₂ represent the brightness and m₁ and m₂ refer to the magnitudes of the stars being compared. One star has a magnitude (m₁) of -1.2, and another star has a magnitude (m₂) of +0.8. What is the ratio of brightness of these two stars?
