Logaritmo

Question 1

Definição

Answer 1

loga(b) = x
A = Base
B = Logaritmando
x = Valor do log
B>0, A>0 e diferente de 1

Question 2

Propriedades

Answer 2

Loga (B.C) = Loga b + loga c
Loga (B/C) = Loga b - loga c
Loga b² = 2 . Loga b
Loga² b = 1/2. Loga b
a^loga(b) = b

Question 3

Mudança de base

Answer 3

Loga B = Logc B/ Logc A

Loga B = 1/ Logb A

Question 4

Cologaritmo

Answer 4

É o valor oposto logaritmo

Cologa B= - Loga B
