Analyzing the spectrum of a distant galaxy, you discover evidence that a type la supernova is occurring in that galaxy. A type la supernova has a peak luminosity of about 10 solar luminosities (1 solar luminosity 3.8e26 Watts). Looking at an image of the galaxy, you estimate that here on ea your telescope only sees a brightness of 8.45E-10 Watts/m². Using this information and the brightness equation, how distant is the galaxy in which the supernova is occurring? Give your answer in It yrs. ly
