Question

Sendo log2=0,30 log3=0,48 e log7=0,54
Calcule o log 54

Answer 1

log 54
log (2.3^3)
log 2 + log 3^3
log 2 + 3log 3
0,30 + 3.0,48
0,30 + 1,44
1,74

Answer 2

$\log_{}2=0,30$

$\log_{}3=0,48$

$\log_{}7=0,54$

$\log_{}54=\log_{}2. 3^{3} =\log_{}2+\log_{} 3^{3} =\log_{}2+3.\log_{} 3 =0,30+3.(0,48)=$$0,30+1,44=1,74$
