Question

ДАЮ 35 БАЛЛОВ!!! Помогите

Answer 1

$(d^{10} + x^{10})^2 - (d^{10} - x^{10})^2-d^2x^2 = \\= d^{100} + 2d^{10}x^{10}+x^{100}-d^{100} + 2d^{10}x^{10} - x^{100} - d^2x^2 = \\= 4d^{10}x^{10}-d^2x^2 = d^2x^2(4d^{8}x^{8}-1)$

AND

$4d^{10}x^{10}-d^2x^2 = d^2x^2(2d^4x^4-1)(2d^4x^4+1)$

Успехов.
