If the operation ∆ is defined by a ∆ b = (b - a)^2/a^2 for all numbers a and b, and a ≠ 0, then what is the result when we evaluate this expression: (-3) ∆ (3 ∆ −3) ?
Answers:
A) 47/6
B) 49/9
C) 36/25
D) 25/16
E) 16/9
(-3) ∆ (3 ∆ − 3) =   (-3) ∆ (6^2/3^2) =   (-3) ∆ (4) =   (-7^2) / (-3)^2 = 49/9   The answer is 49/9.
