Answer 1

${\mapsto} \: {\rm{( {x}^{2} + 4)( {x}^{2} - 4)( {x}^{4} + 16) }}$

Using Identity,

${\bold{\green{\mapsto}}} \: {{\green{\rm{\bold{(a + b)(a -b) = {a}^{2} - {b}^{2} }}}}}$

${\mapsto} \: {\rm{( { {x}^{2}) }^{2} - ( {16})^{2} \: ( {x}^{4} + 16) }}$

${\mapsto}{\rm{ ({x}^{4} - 16)( {x}^{4} + 16) }}$

${\mapsto} \: {\rm{ {( {x}^{4}) }^{2} - ( {16})^{2} }}$

${\mapsto} \: {\rm{ {x}^{8} - 256}}$
