What should replace the question mark?
\[\frac{854 × 854 × 854 - 276 × 276 × 276}{854 × 854 + 854 × 276 + 276 × 276}=?\]
Answer & explanation
Correct answer: option 2
\[\frac{854 × 854 × 854 - 276 × 276 × 276}{854 × 854 + 854 × 276 + 276 × 276}=?\]
(8543 - 2763 )/ (8542 + 2762 + 854*276)
a3-b3 = (a−b)(a2 + b2 + ab)
Thus the expression becomes: (854-276) = 576
The correct answer is Option (2) → 578
