The value of (log9 27 + log8 32) is:	Choose the correct choice from the following choices
A) 7 / 2
B) 19 / 6
C) 5 / 3
D) 7
E) 8

Rationale: let log 9 27 = x . then , 9 x = 27 = > ( 32 ) x = 33 = > 2 x = 3 = > x = 3 / 2 let log 8 32 = y . then 8 y = 32 = > ( 23 ) y = 25 = > 3 y = 5 = > y = 5 / 3 answer : c
Answer: C
