Question

1) Dados log 2=0,30 e log 3=0,47 determine:

a) log 6

b) log 5

c) log 12

d) log 81

e) log 200​

Answer 1

Resposta:

a)0,77

b)0,70

c)1,07

d)1,88

e)2,30

Explicação passo-a-passo:

log2 =0,30 log3 =0,47

log6 >> log2.3 >> log2 + log3 >> 0,30+0,47= 0,77

log5 >> log10/2 >> log10 - log2 >> 1-0,30 = 0,70

log12 >> log2².3 >> 2log2 + log3 >> 2.0,30 + 0,47 = 1,07

log81 >> log3⁴ >> 4log3 >> 4.0,47 = 1,88

log 200 >> log2.100 >> log2 + log100 = 2,30
