Question

Se log 2 = 0,301, então quanto vale o log 160?

Answer 1

log 160 = log 2.2.2.2.10
log2 + log2 + log2 + log2 + log 10

0,301 + 0,301 + 0,301 +0,301 + 1
1,204 + 1 
2,204

Resp: log 160 = 2,204

Answer 2

Se log 2=0,301

$log160 \\ log10+log2^4 \\ 1+4log2 \\ 1+4(0,301 \\ 1+1,204 \\ \fbox{ 2,204 }$
