The formula M = m 5 log (d/10) gives the distance d (in parsecs) from Earth

Question:

The formula M = m − 5 log (d/10) gives the distance d (in parsecs) from Earth to a star with apparent magnitude m and absolute magnitude M. The star Rasalhague has an apparent magnitude of 2.08 and an absolute magnitude of 1.3. Find the distance from Earth to Rasalhague.
