x - (1/x) = √6
பயன்படுத்தப்பட்டுள்ள சூத்திரம்:
x8 - (1/x8) = {x4 + (1/x4)} × {x2 + (1/x2)} × {x + (1/x)} × {x - (1/x)}
கணக்கீடு:
x - (1/x) = √6
x2 + (1/x2) = (√6)2 + 2 = 8
x4 + (1/x4) = (8)2 - 2 = 62
x + (1/x) = √{(√6)2 + 4} = √10
x8 - (1/x8) = {x4 + (1/x4)} × {x2 + (1/x2)} × {x + (1/x)} × {x - (1/x)}
⇒ 62 × 8 × √10 × √6 = 496 × 2 × √15 = 992√15
∴ எனவே சரியான விடை 992√15.
