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?

b1 / b2 = blank ?
