What is the combined apparent magnitude o a binary system consisting of two stars of apparent magnitudes 3.0 and 4.0
Homework Equations
m-n=2.5 log(f(m)/f(n))
The Attempt at a Solution
I know m= 3 and n=4 ,or vice versa. I'm not sure what this problem means by combined magnitude. Do they mean I should add m and n together?
