If abc = ab^3 = 180 where a, b and c are positive integers, what is the value of `c’?	Select:
A) 0	B) 1	C) 2	D) 3	E) 4

Rationale: abc = a ( b ^ 3 ) = 180 on solving abc = a ( b ^ 3 ) we get c = b ^ 2 and for a ( b ^ 3 ) = 180 , there is only one possibility a = 180 and b = 1 so c = 1 ^ 2 = 1 answer : b
Answer: B
