数学题：计算与化简求值：(a=-8,b=-1) 1.(a-2)(a^2+4)(a^4+16) 2.(a-3b)^2+(3a+b)^2-(a+5b)^2+(a-5b)^2

计算与化简求值：(a=-8,b=-1) 1.(a-2)(a^2+4)(a^4+16) 2.(a-3b)^2+(3a+b)^2-(a+5b)^2+(a-5b)^2
要有过程奥迅速抬起头，你的脸色苍白它
更快的释放你的皱纹的额头酒吧
你的生命不长
她不能来，她悲伤的恶劣天气

终于有这样的人在过去

谁生长在一个没有人急于回答问题，让他们都去

据风让过去去

我们在这里等待
我们辛辛
所以不要给你那些东西大麻
这些风暴你不想让他们都去逃避

同风转到好得多

总有一些
这些雨云

对未来，请不要离开你平静

不要离开你等着

Answer 1

1、（a-2)(a^2+4)(a^4+16)
=（a+2)(a-2)(a^2+4)(a^4+16) /（a+2)
=(a^2-4))(a^2+4)(a^4+16)/（a+2)
=(a^4-16))(a^4+16)/（a+2)
=（a^4*a^4-16*16）/(a+2)
=（16*16*16*16-16*16）/(8+2)
=【16*16(16*16-1)】/10
=128*2*255/10
=128*51*2*5/10
=128*51
=128*50+128
=128*100/2+128
=6400+128
=6528
2、(a-3b)^2+(3a+b)^2-(a+5b)^2+(a-5b)^2
=a^2-6ab+9b^2+9a^2+6ab+b^2+(a-5b+a+5b)(a-5b-a-5b)
=10a^2+10b^2-20ab
=10(a-b)^2
=10*9^2
=10*81
=810

Answer 4

Quickly looked up and your pale face it
faster release your wrinkled brow bar
that your life is not long
she can not she come to grief those bad weather

finally people are like this in the past

who grew up in a hurry no one to answer questions and let them all go

far as the wind let the past go to

We are here waiting for
we sing Sing
so do not give you those things cannabis
those storms you do not want to let them all go to escape

Go with the wind far better

will always have some
those storm clouds

about the future, please do not leave you calm

Do not leave you waiting
