8

Respuesta:

A = 8 espero que te ayude

Explicación paso a paso:

m^{4}-n^{4}  =8=(m^{2}+n^{2})(m^{2}-n^{2})

m^{2}-n^{2}=2

m^{4}-n^{4}  =8\\(m^{2}+n^{2})(m^{2}-n^{2})=8\\(m^{2}+n^{2})(2)=8\\(m^{2}+n^{2})=4\\

A=(m+n)^{2} +(m-n)^{2}

A= m^{2}+2mn+n^{2}+m^{2}-2mn+n^{2} =2m^{2}+2n^{2}=2(m^{2}+n^{2})\\2(4) = 8
