These problems review skills from earlier lessons.

Which statement correctly describes what $\log_{10} 1000$ equals and why?

3, because $10^3 = 1000$

100, because $\log_{10} 1000 = 1000 \div 10$

4, because $\log_{10} 1000 = \log_{10} 10 \times \log_{10} 100$

30, because $\log_{10} 1000 = 10 \times 3$
