Question

Dados log2=0,30 log3=0,48 e log7=0,85 calcule:

A) log 35
B) log 150

Answer 1

log 35 = log 7.5
log 7 + log5
log 7 + log 10/2
log 7 + log 10 - log2
0,85 + 1 - 0,30
1,55

log 150 = log 2.3.5.5
log 2 + log 3 + log 5 + log 5
log 2 + log 3 + log 10/2 + log 10/2
log 2 + log 3 + log 10 - log 2 + log 10 - log 2
0,30 + 0,48 + 1 - 0,30 + 1 - 0,30
2,18
