Question

dados log 2 =0,3 , log 3=0,48 , log 5=0,7 e log 7=0,85 , calcule : A- log 03 , B- log 45 , c- log 250 , d- log 5

Answer 1

Boa noite Biell

log(2) = 0.30
log(3) = 0.48
log(5) = 0.70 
log(7) = 0.85 

a) log(3) = 0.48
b) log(45) = log(9*5) = 2log(3) + log(5) = 0.96 + 0.70 = 1.66 
c) log(250) = log(5*5*10) = 2log(5) + log(10) = 1.4 + 1 = 2.4
d) log(5) = 0.70
