a3 + b3 = (a + b)(a2 + b2 - ab)
গণনা:
⇒ \(\frac{432× 432+247× 247-432× 247}{432× 432× 432+247× 247× 247}\)
⇒ \(\frac{(432)^2 + (247)^2 - 432 × 247}{(432)^3 + (247)^3}\)
⇒ \(\frac{[(432)^2 + (247)^2 - 432 × 247]}{[(432) + (247)](432^2 + 247^2 - 432 \times 247)}\)
⇒ \(\frac{1}{432 + 247}\)
⇒ \(\frac{1}{679}\)
∴ সঠিক উত্তর 1/679
