——————————————————————————————————————①|-13|+|-53|+(-21)+|-3.5+3.5|
=13+53-21+0
=66-21
=45
②(-3又4分之1)+(+3又3分之2)+(+2又4分之1)+(-1又3分之2)
=-3又4分之1+3又3分之2+2又4分之1-1又3分之2
=-3又4分之1+2又4分之1+3又3分之2-1又3分之2
=-1+2
=1
③(-1×1/2)+(-1/2×1/3)+(-1/3×1/4)+......+(-1/2007×1/2008)
=(-1)[(1-1/2)(1/2-1/3)(1/3-1/4)+...+(1/2007-1/2008)]
=(-1)(1-1/2008)
=-2007/2008
④(-7.33)×(+42.07)+(-2.07)(-7.33)
=(-7.33)×(42.07-2.07)
=(-7.33)×40
=-293.2
⑤若设x=(-1/1996)^2005×1996^2006;y=(-5)^2005×(-6)^2005×(-1/30)^2004-34,求(x+y)^4的值;并用科学计数法表示结果

x=(-1/1996)^2005×1996^2006=(-1)^2005*1996^2006/1996^2005=-1996
y=(-5)^2005×(-6)^2005×(-1/30)^2004-34
=[(-5)*(-6)]^2005*(-1)^2004/30^2004-34
=30-34
=-4
(x+y)^4=(-1996-4)^4=(-2000)^4=16×10^12
=1.6×10^13
够多了;分给我吧。求.........
