Question

Qual o log 1/3 na base 2,7?​

Answer 1

Resposta:

2,7=27/10=3³/10

log 1/3 na base 2,7

ou

log 3⁻¹ na base 3³/10

### log[a] b = log b/log a

### log 10 =1

### log a/b = log a- log b

### log a^b = b* log a

= log 3⁻¹  / log(3³/10)

= -log 3  / [log(3³)- log 10]

= -log(3)  / [3*log(3)- 1]
