Algebra Challenge

If you're a fan of math (I'm not,) there a whole division of challenges you could play with. For instance, below is an algebraic problem in which you must convert a complex fraction into a simple one...

1) Solve and choose the closest answer:

y² m⁴ b x⁶ a z³ n⁸
n⁷ b y² m³ x⁶ a^-2 z³
-
r³ h² u² q³ b² k³ a³ e t⁵ p² k w⁸ s⁴
w⁶ h q² k³ a ^-2 t⁴ p r h u² r² w² p a^-2 b q e k^-2 b q e k^-2 s⁴

A) Aquaman
B) Hawkman
C) Superman
D) Man-Bat
E) I Don't Know

Even with a vague recollection of high school math, you may notice the shorter first fraction followed by a minus sign, indicating the first "word" would likely be shorter, and that there might be a hyphen between the "words." If you successfully reduced the problem you would find the answer is Man-Bat.
