Question

Como cálculo log 5x10^-3/2x10 ? (Favor demonstrar o passo a passo)

Answer 1

$log\,{5}\,\,\times\,\dfrac{1}{2\sqrt{10^2}}\times10$

$log\,{5}\,\times\,\dfrac{1}{2\sqrt{100}}\,\times10$

$log\,{5}\,\times\dfrac{1}{2\times10}\,\times10$

$log\,{5}\,\times\,\dfrac{1}{20}\,\times10$

$log\,{5}\times\,\dfrac{10}{20}=log\,{5}\times\dfrac{1}{2}$

$0,698\times\dfrac{1}{2}=\dfrac{0,698}{2}$

$=0,349$
