8k6 + 15k3 – 2 = 0
గణన:
k3 = x
కాబట్టి, 8x2 + 15x - 2 = 0
⇒ 8x2 + 16x - x - 2 = 0
⇒ 8x (x + 2) - 1 (x + 2) = 0
⇒ (8x - 1) (x + 2) = 0
⇒ 8x - 1 = 0 ⇒ x = 1/8
⇒ x + 2 = 0 ⇒ x = - 2 [ప్రతికూల విలువ కారణంగా సాధ్యం కాదు]
ఇప్పుడు, k3 = 1/8
⇒ k = 1/2 ⇒ 1/k = 2
అప్పుడు, (k + 1/k) = (1/2 + 2) = 5/2 =
∴(k + 1/k) విలువ
