Question

Si se considera que log2 = 0,3 y log 3 =0,48
Calcula los siguientes logaritmos, aplicando las propiedades:
a) log 6 =
b) log 9 =
c) log1/8 =
d) log20=​

Answer 1

Respuesta:

a) log 6 = log ( 3 x 2 ) = log3 + log2 = 0.48 + 0.3

= 0.78

b) log 9 = log 3² = 2log 3 = 2(0.48) = 0.96

c) log 1/8 = log1/2³ = log 1 - 3log2 = o - 3(0.3)

= -0.9

d) log 20 = log ( 10x2) =log10 + log 2 = 1 + 0.3

= 1.3
