Question

Pode-se afirmar que o valor de log 18 é igual a: a) log 20 – log 2 b) 3 log 6 c) log 3 + log 6 d) 2 log 36 e) (log 3) (log 6)​

Answer 1

$\large\boxed{\begin{array}{l}\sf \ell og18=\ell og(3\cdot6)\\\sf \ell og18=\ell og3+\ell og6\\\huge\boxed{\boxed{\boxed{\boxed{\sf\dagger\red{\maltese}~\blue{alternativa~c}}}}}\end{array}}$
