Question

06. Se log10 (2)=0,3 e log10 (3)=0,4, determinar:

a) log10 (18)

b) log10 (16)

c) log10 (50)

d) log10 (250)

Answer 1

a) log18=log(9.2)=log9 +log2....log3² +log2.... 2.log3 +log2=2.0,4 +0,3=1,1
b)log16=log2^4 =4.log2 =4.0,3=1,2
c)log50=log(100/2)=log100 -log2 =2 -0,3=1,7
d)log250=log(1000/4)=log1000 -log2²=3-2.log2=3  - 2.0,3 = 2,4
