1.化简(5a^2+2a-1)-4(3-8a+2a^2)
1.化简(5a^2+2a-1)-4(3-8a+2a^2)
1.化简(5a^2+2a-1)-4(3-8a+2a^2)
=5a^2+2a-1-(12-32a+8a^2)
=5a^2+2a-1-12+32a-8a^2
=34a-3a^2-13
化简; a-2a+3a-4a+5a-6a+``````-2006a+2007a.
化简:a-2a+3a-4a+5a-6a+.+2010a+2011a.
a+a+1+a+2+a+3+a+4+a+5+a+6+a+7.+a+2013+a+2014=?
求和:1,a+a^2,a^3+a^4+a^5,a^6+a^7+a^8+a^9,···(a不等于0)
5a-【a+(5a-2a)-2(a-3a)-4a】
化简(—a^3+3a^2-7a+5)+(5a^-6a)-(a^3-4a+7)
化简(—a^3+3a^2-7a+5)+(5a^-6a)-(a^3-4a+7)
a=-1 求a-2a+3a-4a+5a-6a+...+99a-100a
化简 3a-[5a-(a+2)+a]-1
判断1.√16^4=4a^2 2.√5a*√10a=5√2*a 3.a√1/a=√a^2.1/a=√a 4.√3a-√2a=√a3.a√1/a=√a^2再乘1/a(同一根号)=√a
2a*a+3a+2/a+1-a*a-a-5/a+2-3a*a-4a-5/a-2+2a*a-8a+5/a-3
化简:a(a*a-1)+2a*a(a+1)-3a(2a-5)拜托了各位
化简 a-2a+3a-4a+5a'''''''+99a-100a a=-2 的值
化简a+2a-3a-4q+5a+6a-7a-8a+...2001a+2002a-2003a-2004a
化简:3a-[5a-(2a-1)]=
1.化简(5a^2+2a-1)-4(3-8a+2a^2)
