The difference between the apparent magnitude (brightness) m of a star and its absolute magnitude M is given by the formula m − M = 5log d/10, where d is the distance of the star from Earth, measured in parsecs. Find the distance d of a star with an apparent magnitude of 7.0 and an absolute magnitude of −0.2. Round your answer to the nearest tenth. The star is about parsecs from Earth
