(1)3(2a+1)+2(3-a) (2)3m-2n+[-4m-(3m-n)]+(m-3n)要过程的!
(1)
3(2a+1)+2(3-a)
=6a+3+6-2a
=6a-2a+9
=4a+9
(2)
3m-2n+[-4m-(3m-n)]+(m-3n)
=3m-2n+[-4m-3m+n]+m-3n
=3m-2n+[-7m+n]+m-3n
=3m-2n-7m+n+m-3n
=-3m-4n
(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=?
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^2-4/(a-3)(a+2)+(a+2)/a-3]除以a+1/a-3
[a/(a-1)+a/(a+2)](a+2)/(2a平方+3a+1)化简
(a+1/a方-a+4/1-a方)/a方+2a-3/a+3
求和:1/a+2/a^a+3/a*a*a+...+n/a的n次方
已知a×a+a-1=0求a*a*a+2a+3
因式分解 a^3+a^2-a-1
(a+1)(a+2)(a-3)计算
1A,2A,3A...
