The answer is not 21.7416. I need help! Thank you!

If a quasar is 1,980 times more luminous than an entire galaxy, what is the absolute magnitude of such a quasar? (Note: The absolute magnitude of the Milky Way Galaxy is about −21. *Hint*: Use the formula for magnitudes and flux ratios, \( m_B = m_A - 2.5 \log \left( \frac{F_A}{F_B} \right) \)). [Input box with the value "21.7416" marked incorrect]
