Question

Urgente ajuda! determine log 1/32 na base 4 + log 0,0001 - log10 raiz 10

Answer 1

Resposta:

Explicação passo-a-passo:

log4 (1/32) + log 0,0001 - log 10√10 =

log (1/32)/log 4 + log 10∧(-4) - log √(10.10²) =

log (1/32) - log 4 - 4log 10 - log √(10³) =

(log 1 - log 32) - log 4 - 4log 10 - log √(10³) =

log 1 - log 2∧5 - log 2² - 4log 10 - log (10³)∧(1/2) =

log 1 - 5log 2 - 2log 2 - 4log 10 - (3/2)log 10 = (㏒ 2=0,301, ㏒ 1 =0, ㏒ 10=1)

0 - 5.(0,301) - 2.(0,301) - 4.1 - (3/2).1 =

- 1,505 - 0,602 - 4 - 1,5 =

- 7,607.
