Question

Dados log 2 = 0,301 , log 3 = 0,477 . Calcule ?

a)log 9


b)log 4


c)log 12

Answer 1

Explicação passo-a-passo:

a)

log 9=log(3.3)

log9= log3 + log3

log9=0,477+0,477=0,954

b)

log 4=log(2.2)

log4= log2 + log2

log4=0,301+0,301=0,602

c)log 12=log(3.2.2)

log12=log3+log2+log2

log12=0,477+0,301+0,301

log12= 0,477 + 0,602= 1,079
