PUERTA | PUERTA CS 2011 | Pregunta 65 – Part 6

Si Log(P) = (1/2)Log(Q) = (1/3)Log(R), ¿cuál de las siguientes opciones es VERDADERA ?
(A) P ² = Q ³ R ²
(B) Q ² = PR
(C) Q ² = R ³ P ²
(D) R = P ² Q ²

Respuesta: (B)
Explicación:

It is given that Log(P) = (1/2)Log(Q) = (1/3)Log(R)

Let Log(P) = (1/2)Log(Q) = (1/3)Log(R) = C

Let the base of log be B

P = BC
Q = B2C
R = B3C

Which means Q2 = PR
