Question

calcule o valor de log 216 - log 2,16

Answer 1

$\mathsf{\ell og(216)-\ell og(2,16)\Rightarrow \ell og(216)-\ell og(\frac{216}{100})\Rightarrow \ell og\Big(\dfrac{216}{\dfrac{216}{100}}\Big)}\\\\\mathsf{\ell og\Big(\diagup\!\!\!\!\!216\cdot\dfrac{100}{\diagup\!\!\!\!\!216}\Big)\Rightarrow \ell og(100)=2}$
