Question

se log 2345 =3,37 , então determine o valor de
A) log23,45
B) log2,345
C) log0,02345
D) log234500

Answer 1

$a) \ log23,45=log \frac{2345}{100}=log2345-log100=3,37-2=1,37\\ \\ b) \ log2,345=log \frac{2345}{1000}=log2345-log1000=3,37-3=0,37\\ \\ c) \ log0,02345=log \frac{2345}{100000}=3,37-5=-1,63\\ \\ d) \ log234500=log2345*100=log2345+log100=3,37+2=5,37$
