Exponential and logarithmic functions
The difference in brightness between two stars is given by the formula m2-m1=log(b1/b2) where m is the apparent magnitude of each star (the intensity of its brightness) and b, the actual amount of light it emits.
a) If two stars have apparent magnitudes of 0.5 and 3.1 respectively, how many times brighter is one star than the other?
b) What is the magnitude of a star that is 2.5 times brighter than a star of magnitude 0?
