(a + 1/a) = P ; பிறகு
(a 2 + 1/a 2 ) = P 2 - 2
(a 3 + 1/a 3 ) = P 3 - 3P
கணக்கீடு:
a + (1/a) = 7
⇒ (a 2 + 1/a 2 ) = (7) 2 - 2 = 49 - 2 = 47
⇒ (a 3 + 1/a 3 ) = (7) 3 - (3 × 7) = 343 - 21 = 322
a 5 + (1/a 5 ) = (a 2 + 1/a 2 ) × (a 3 + 1/a3 ) - (a + 1/a)
⇒ 47 × 322 - 7
⇒ 15134 - 7 = 15127
∴ சரியான பதில் 15127.
