பயன்படுத்தப்பட்ட கருத்து:

• (x + 1/x) = a என்றால், பிறகு (x - 1/x) = √(a2 - 4) ஆக இருக்கும்

• If x + 1/x = a என்றால், பிறகு (x3 + 1/x3) = a3 - 3a ஆக இருக்கும்

• If x - 1/x = a என்றால், பிறகு (x3 - 1/x3) = a3 + 3a ஆக இருக்கும்

கணக்கீடு:

\(\rm \left(x+\frac{1}{x}\right)=2√2\), பிறகு (x - 1/x) = √(8 - 4) = 2 ஆக இருக்கும்

\(\rm \left(x^6-\frac{1}{x^6}\right)\)

⇒ (x3)2 - (1/x3)2

⇒ (x3 + 1/x3) (x3 - 1/x3)

⇒ [(2√2)3 - 3(2√2)] [23 + 3 × 2]

⇒ [16√2 - 6√2] × 14

⇒ 10√2 × 14

⇒ 140√2

∴ சரியான பதில் 140√2
