Ajuda Questão de Matemática???

1)Com Log a = 5,Log b = 2 e Log c = -1 Calcule:
x x x

Log a² b³
x ____
c4

Answer 1

(Log a².b³)/c^4 =
(Log a² + Log b³) / (-1)^4 =
(2Log a + 3Log b) / 1 =
(2 . 5 + 3 . 2) = 10 + 6 = 16

Answer 2

log a²*b³ = log a² + log b³ = 2 * log a + 3 * log b = 2 * 5 + 3 * 2 = 10 + 6 = 16
