Answer 1

Answer:

${x}^{4} + \frac{1}{ {x}^{4} } = 23$

Step-by-step explanation:

${x}^{2} + \frac{1}{ {x}^{2} } = 5 \\ Squaring \: on \: both \: the \: sides \\ {( {x}^{2} + \frac{1}{ {x}^{2} } ) }^{2} = {(5)}^{2} \\ {x}^{4} + \frac{1}{ {x}^{4} } + 2 = 25 \\ {x}^{4} + \frac{1}{ {x}^{4} } = 25 - 2 \\ {x}^{4} + \frac{1}{ {x}^{4} } = 23$
