$\sf{ \boxed{ \blue{(a ^{2} + b ^{2} ) \: ( - a ^{2} + b^{2} )}}}$

$\sf \implies( b ^{2} + a ^{2} ) \: (b ^{2} - a ^{2} )$

$\implies \sf(b^{2}) ^{2} -( a ^{2}) ^{2}$

$\sf \implies \green{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: using \:identity \: III}$

$\sf \implies {\boxed {\orange{b^{4} - a ^{4} }}}$
