Question

todas as formulas de logaritmo e quando usa-lás??

Answer 1

$\text{log}_{\text{a}}\text{b}=\text{x}\Rightarrow\text{a}^{\text{x}}=\text{b}$

 

$\text{log}_{\text{a}}\text{b}=\text{x}\Rightarrow\text{anti}~\text{log}_{\text{a}}\text{x}$

 

$\text{co}~\text{log}_{\text{a}}\text{b}=-\text{log}_{\text{a}}\text{b}=\text{log}_{\text{a}}\frac{1}{\text{b}}$
