Inverse square law.....intensity-brightness-luminosity-distance

recall the inverse square law of intensity of light and use it to relate the brightness of a star to its luminosity and distance from an observer.

I would recommend three things: first look up the "inverse square law" and write it down. Second, look up the definition of "brightness". Third, look up the definition of "luminosity".

Now think carefully about the difference between "brightness" and "luminosity" of a stand and put those three things together.
