a(a-1)(a-2)(a-3)(a-4)因式分解a(a-1)(a-2)(a-3)(a-4)因式分解a(a-1)(a-2)(a-3)(a-4)因式分解这是求值,不是因式分a(a-1)(a-2)(a-3
a(a-1)(a-2)(a-3)(a-4)因式分解
a(a-1)(a-2)(a-3)(a-4)因式分解
a(a-1)(a-2)(a-3)(a-4)因式分解
这是求值,不是因式分
a(a-1)(a-2)(a-3)(a-4)
=a(a-1)(a-4)(a-2)(a-3)
=a(a^2-5a+4)(a^2-5a+6)
=a[(a^2-5a)^2+10(a^2-5a)+24}
=a[a^4-10a^3+25a^2+10a^2-50a+24]
=a^5-10a^4+35a^3-50a^2+24a
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=[ ]
a+a+1+a+2+a+3+a+4+a+5+a+6+a+7.+a+2013+a+2014=?
幂的计算题1、a×a^2×a^3×a^4×a^52、a+2a+3a+4a+a×a^2×a^3×a^4
(a 1)(a 2)(a 3)(a
(a+2)(a+1)-a(a-3)
[a^2-4/(a-3)(a+2)+(a+2)/a-3]除以a+1/a-3
(a+1/a方-a+4/1-a方)/a方+2a-3/a+3
a=-1 求a-2a+3a-4a+5a-6a+...+99a-100a
(a+4)(2a+1)(a-3)
计算;(a^3)^4+a^10×a^2-a×a^2-a*a^3*a^8
a-2a+3a-4a+5a-6a+...+99a-100a
化简; a-2a+3a-4a+5a-6a+``````-2006a+2007a.
(a+3a+5a+...+2009a)-(2a+4a+6a+...+2008a)=
(a+3a+5a+.+2009a)-(2a+4a+6a+.2008a)
计算（a+3a+5a+...+2009a)-(2a+4a+6a+...+2010a)
(a+3a+5a+...+2013a)-(2a+4a+6a+...+2012a)=
化简：a-2a+3a-4a+5a-6a+.+2010a+2011a.
