Question

alguem me ajuda pfv ​

Answer 1

Resposta:

Explicação passo a passo:

$log\:(a.b)=log\:a+log\:b$

$log\:(a/b)=log\:a-log\:b$

$log\:a^{m}=m\:.\:log\:a$

$log\:10=1$

$log\:2=0,3$

$log\:3=0,47$

$log\:\frac{8\:.\:\sqrt{2} }{10} =log\:8.\sqrt{2}\:\:-\:\:log\:10=log\:8+log\:\sqrt{2} -log\:10=$

$log\:2^{3}\:+\:log\:2^{\frac{1}{2} }-1=3\:.\:log\:2+\frac{1}{2}\:.\:log\:2-1=$

$3\:.\:(0,30)+\frac{1}{2}\:.\:(0,30)-1=$

$0,9+0,15-1=1,05-1=0,05$

$Resposta:0,05$
