分子立方差
原式=[a^(1/3)-1][a^(2/3)+a^(1/3)+1]/[a^(2/3)+a^(1/3)+1]
=a^(1/3)-1
(a 1)(a 2)(a 3)(a
(a+2)(a+1)-a(a-3)
a(a-1)(a-2)(a-3)(a-4)因式分解
【1】a+a=a×a a= [ ]【2】a×a=a÷a a=[ ]【3】a×a=a－a a=[ ] [4]a－a=a＋a a=[ ]
(通分） a/a^a^a+3a+2 ,a/a^a+2a+1 ,-1/3a+6
（a-a/a+1)/(a*a-2a)*(a+1)/(a*a+3a+2)要详细的计算说明！
a+a+1+a+2+a+3+a+4+a+5+a+6+a+7.+a+2013+a+2014=?
