Question

2. Escreva na forma de um único logaritmo:
a) LOG5 6 + LOG5 8 =
b) LOG3 9 – LOG3 3 =
c) 5. LOG 3 =
d) 2+ LOG4 2 =

Valendo 50 pontos, PRECISO URGENTEEE

Answer 1

logc a + logc b = logc (a.b)

logc a - logc b = logc (a/b)

logb a^c = c . logb a

a)

log5 6 + log5 8

log5 (6.8)

log5 (48)

b)

log3 9 - log3 3

log3 (9/3)

log3 3

c)

5 . log 3

log 3^5

d)

2 + log4 2

log4 16 + log4 2

log4 (16.2)

log4 32
