We Have

(i).

$x + \frac{1}{x} = 4$

$⇒(x + \frac{1}{x} {)}^{2} = {4}^{2}$

$\sf \colorbox{pink} {\red[on Squaring both sides]}$

$⇒ {x}^{2} + \frac{1}{ {x}^{2} } + 2 \times x \times \frac{1}{x} = 16$

$⇒ {x}^{2} + \frac{1}{ {x}^{2} } + 2 = 16$

$⇒ {x}^{2} + \frac{1}{ {x}^{2} } = (16 - 2)$

$⇒ {x}^{2} + \frac{1}{ {x}^{2} } = 14$

(ii).

${x}^{2} + \frac{1}{ {x}^{2} } = 14$

$⇒( {x}^{2} + \frac{1}{ {x}^{2} } {)}^{2} = {(14)}^{2}$

$\sf \colorbox{pink} {\red [on Squaring both sides]}$

$⇒ {x}^{4} + \frac{1}{ {x}^{4} } + 2 \times {x}^{2} \times \frac{1}{ {x}^{2} } = 196$

$⇒ {x}^{4} + \frac{1}{ {x}^{4} } + 2 = 196$

$⇒ {x}^{4} + \frac{1}{ {x}^{4} } = (196 - 2)$

$⇒ {x}^{4} + \frac{1}{ {x}^{4} } = 194$
