15a^3+10a^2
15a^3+10a^2
15a^3+10a^2
貌似不清楚你要做什么呀?
15a^3+10a^2=5a^2(3a+2)
是问因式分解吗
5a^2(3a+2)
什么意思啊???
计算;(a^3)^4+a^10×a^2-a×a^2-a*a^3*a^8
a-2a+3a-4a+5a-6a+7a-8a+9a-10a+11a.+99a-100a=
15a^3+10a^2
15a^3+10a^2
化简10+3a-a^2/2+a-a^2
下列计算正确的是( )A .a^5-a^3=a^2 B.a^5*a^3=a^15 C.4^6/a^3=a^2 D.(-a^5)^2=a^10
合并同类项:a-2a-3a+4a+5a-6a-7a+8a+9a-10a-11a+12a+……+2008a+2009a-2010a-2011a
5a^ 2+【a^ 2+15a^ 2-a)-2(a^ 2-3a)】
5a^ 2+【a^ 2+15a^ 2-a)-2(a^ 2-3a)】
逻辑运算中A表示什么 (1) 0 · A = 0 (10) 1' = 0; 0' = 1 (2) 1 · A = A (11) 1 + A = 1 (3) A · A = A (12) 0 + A = A (4) A · A' = 0 (13) A + A = A (5) A · B = B · A (14) A + A' = 1 (6) A·(B·C) = (A·B)·C (15) A
快 2a-10/9-6a+a²÷(a²-25)*3a²+15a/5-a化简 2a-10/9-6a+a²÷(a²-25)*3a²+15a/5-a 20分钟内做出我给100悬赏分啊,化简 (2a-10)/(9-6a+a²) ÷ (a²-25) * (3a²+15a)/(5-a ) / 为分数线
计算(3a×a)+(2a×3a)+(3a×a)+[a×(a+2a+2a+2a+a)]
a-2a-3a+4a+5a-6a-7a+8a+9a-10a-11a.+2008a+2009a-2010a-2011a如何合并同类项?

(a 1)(a 2)(a 3)(a
(a+2)(a+1)-a(a-3)
已知a^2+a=1/3 求6a^4+15a^3+10a^2的值
15a的3次方+10a平方等于 5a(3a+2)3后面的a是怎么回事.
