<p>Let k<sup>3</sup> = x<sup> </sup>, then</p>

<p>8k<sup>6</sup> + 15k<sup>3</sup> - 2 = 0 becomes 8x<sup>2</sup> + 15x - 2 = 0</p>

<p>⇒ 8x<sup>2</sup> + 15x - 2 = 0 ⇒ 8x<sup>2</sup> + 16x - x - 2 = 0</p>

<p>⇒ 8x(x + 2) - 1(x + 2) = 0</p>

<p>⇒ (8x - 1)(x + 2) = 0 </p>

<p>Either 8x - 1 = 0 or x + 2 = 0 </p>

<p>⇒ Either x = 1/8 or -2</p>

<p>We have to find the positive value of {k + 1/k} so x cannot be negative.</p>

<p>Thus, x = 1/8</p>

<p>⇒ k<sup>3</sup> = 1/8 ⇒ k = 1/2 </p>

<p>k + 1/k = 1/2 + 2 = 2<span class="math-tex">\(\frac{1}{2}\)</span></p>
