Homework Help: Help me rearrange this!

  1. Nov 3, 2007 #1
    ok i want d the subject in:
    m - M = 5 (log d) - 5

    ok now.
    (m - M) + 5 = 5(log d)

    ((m - M) + 5) / 5 = log d

    d = 10 ^ ((m - M) +5) / 5)

    is that right?

    Yes, assuming the log is base 10.

    yes im pretty sure it is. everything i have seen on the equation (its the equation to work out distance from absolute and apparent magnitude) has nothing other than base 10. so assuming base 10 cool :D
