Q. If `log_x a, a^(x/2)` and `log_b x` are in G.P. then x is equal to (1) `log_a(log_b a)` (2) `log_a(log_e a)+log_a log_b b` (3)`-log_a(log_a b)` (4) none of these

A

`log_(a) (log_(b) a)`

B

`log_(a) (log_(e)a) - log_(a) (log_(e) b)`

C

`-log_(a) (log_(a) b)`

D

`log_(a) (log_(e) b) - log_(a) (log_(e) a)`
