For a three-digit number xyz, where x, y, and z are the digits of the number, f(xyz)=5^x 2^y 3^z . If f(abc)=3*f(def), what is the value of abc-def ?
Choose the correct choice from the following:
A) 1
B) 2
C) 3
D) 9
E) 27
Since f(abc) = 3*f(def), I would assume that f = c - 1 from the function above.   The answer should be (1)
<result>A</result>
