Answer 11

Okay here we go.

log without a base means that the base here is 10. So a smart way of doing this one is to raise both sides to the power of 10.

\[10^ ((\log_{10} 5x)) = 10^3\]

This would later simplify to:
5x = 10^3.

because a log of a certain base is raised to the power of the same base they cancel off.
