I don't know how to solve this problem. I don't have the distance or the absolute magnitude of the star and the question is confusing.

    $\begingroup$ The star will appear to be 4 times brighter (due to the inverse square law and the distance being 1/2). So what is the apparent magnitude that equates to a brightness ratio of 4? That is the question. $\endgroup$ – JohnHoltz Jun 18 at 19:34

    $\begingroup$ Hi, we encourage people to post what work they've done so far when asking homework or homework-like problems. Further, was that the exact wording of the question? it would be good to know if it's asking for the value of the absolute or apparent magnitude. $\endgroup$ – Carl Witthoft Jun 19 at 18:06
