If 3-²A/1-3²A=K where k is a real number, then A(3 A-4³A) is equal to
Elementary MathematicsTrigonometry
- A2K/K-1
- B2K/K-1, where 1/3 ≤ K ≤ 3
- C2K/K-1, where K 3
- D2K/K+1
Explanation
DISPUTED — the formulae are garbled in the source (exponents unreadable) and no consistent reconstruction was found; the question cannot be solved reliably. Stored key A retained; key disputed.
