Answer 1

$\footnotesize \quad (x + \frac{1}{x} )(x - \frac{1}{x} )( {x}^{2} + \frac{1}{ {x}^{2} } )( {x}^{4} + \frac{1}{ {x}^{4} } )$

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

$\footnotesize = ( {x}^{4} - \frac{1}{ {x}^{4} } )( {x}^{4} + \frac{1}{ {x}^{4} } )$

$\footnotesize = {x}^{8} - \dfrac{1}{ {x}^{8} }$
