Question

mee ajudem a responder essas gentee!!!
CONSIDERANDO OS LOGARITMOS CONHECIDOS LOG2,LOG3,LOG7 DETERMINA OS VALORES DE:
a) log 60=
b) log 50=
c) log 48=
d) log 120=

Answer 1

Vamos lá

log(2) = 0.30103,  log(3) = 0.47712

a) log(60) = log(2) + log(3) + log(10)

log(60) = 0.30103 + 0.47712 + 1 = 1.77815

b) log(50) = log(100/2) = log(100) - log(2)

log(50) = 2 - 0.30103 = 1.69897

c) log(48) = log(3*16) = 4log(2) + log(3)

log(48) = 4*0.30103 + 0.47712 = 1.68124
