What is the value of (log2 3)(log3 4)(log4 5)...(log63 64)?  Choose the correct option.
A) 1 / 6	B) 2	C) 5 / 2	D) 6	E) 32

Rationale: using the identity ( loga b ) ( logb c ) = loga c repeatedly , we obtain ( log 2 3 ) ( log 3 4 ) ( log 4 5 ) . . . ( log 63 64 ) = log 2 64 = 6 correct answer d
Answer: D
