If a^x = b^y, then:

log $\frac {a } {b }$ = $\frac {X } {Y }$

$\frac { loga } { logb }$ = $\frac {X } {Y }$

$\frac { loga } { logb }$ = $\frac {Y } {X }$

None of these

Answer : Option C

Explanation :

a^x = b^y

log a^x = log b^y

x log a = y log b

$\frac { loga } { logb }$ = $\frac {Y } {X }$
