DIRECTIONS for questions: Answer the questions on the basis of the tables given below. Two binary operations and * are defined over the set {a, e, f, g, h} as per the following tables:
Thus, according to the first table f g = a, while according to the second table g * h = f, and so on. Also, let f2 = f * f, g3 = g * g* g, and so on.
Upon simplification, {a10 * (f10 g9)} e8 equals:
