(a+2)(a^2+4)(a^4+16)(a-2),用平方差公式计算,^后面是平方
问题描述:
(a+2)(a^2+4)(a^4+16)(a-2),用平方差公式计算,^后面是平方
答
原式=(a+2)(a-2)(a^2+4)(a^4+16)
=(a^2-4)(a^2+4)(a^4+16)
=(a^4-16)(a^4+16)
=a^8-256
希望我的回答对你有帮助,谢谢
答
(a+2)(a^2+4)(a^4+16)(a-2),
=(a-2)(a+2)(a^2+4)(a^4+16)
=(a^2-4)(a^2+4)(a^4+16)
=(a^4-16)(a^4+16)
=a^8-256
答
(a+2)(a^2+4)(a^4+16)(a-2)
=(a-2)(a+2)(a^2+4)(a^4+16)
=(a²-4)(a²+4)(a^4+16)
=(a^4-16)(a^4+16)
=a^8-256
