could really use some help I'm staring to get a little freaked out.

Question

The flux ratio of two stars is 24. What is their magnitude difference? Use the formula below, and express your answer to 1 decimal place

Answer 1

The problem statement did not provide the formula.  I assume you meant the formula

 

m₁ - m₂ = 2.5 log(L₂/L₁)

 

L = flux

 

L₂/L₁ = 24

 

m₁ - m₂ = 2.5 log(24) ≅ 3.5
