Answer 1

→ Lembrete:

⇒$\log \left(a\cdot b\right)=\log \:\left(a\right)+\log \:\left(b\right)$
⇒$\log \left(10\right)=\log _{10}\left(10\right)=1$
==========
$\log \left(5\right)+\log \left(200\right)\\\log \left(5\cdot 200\right)\\\log \left(1000\right)\\\log \left(10^3\right)\\3\cdot \log \left(10\right)\\\boxed{\bold{3}}$
