2. The absolute magnitude (M) of a star is the apparent magnitude (m) the star would have if it were located at 10 parsecs. Since a difference of five magnitudes corresponds to a factor of $\frac{F_a}{F_b} = 100^{(m_b - m_a)/5}$. Use this, the definition of absolute magnitude M, and your result from (1) to show that a stars distance modulus, $m - M$, is given by $m - M = 5 \log_{10}(d) - 5$, where d is measured in parsecs.
