Answer 1

Respuesta:

Explicación paso a paso:

$a).(7 {x}^{3 } - 4 {y}^{8} )^{2} = \\ =(7 {x}^{3} {)}^{2} - 2(7 {x}^{3} ) (4 {y}^{8} {)}^{2} + (4y^{8})^{2} \\= 49 {x}^{6} - 56 {x}^{3} {y}^{8} + 16 {y}^{16}\\b) . (6mn^{5}+7p)^{2}=\\</p><p>=(6mn^{5})^{2}+2(6mn^{5})(7p)+(7p)^{2}\\=36mn^{2}n^{10}+84mn^{5}p+49p^{2}\\c. (11x^{2}-3y^{3})^{2}=\\ =(11x^{2})^{2} -2(11x^{2})(3y^{3})+(3y^{3})^{2}\\=121x^{4} -66x^{2}y{3}+9y^{6}$
