Question

1) Dados log 2 = 0,30 , log 5 = 0,70 e log 3 = 0,47 ; calcular o log 60: *

A)1,47
B)1,60
C)1,77
D)2,10​

Answer 1

Resposta:

c)1,77

Explicação passo-a-passo:

Answer 2

$\log(60)=\\\\\log(2^2\cdot3\cdot5)=\\\\\log(2^2)+\log(3)+\log(5)=\\\\2\log(2)+\log(3)+\log(5)=\\\\2(0.3)+(0.47)+(0.7)=\\\\0.6+0.47+0.7=\\\\1.77$
