化简:|m|+|m-1|+|m-2|.

当m<0时,m-1<0,m-2<0,原式=-m+1-m+2-m=3-3m;当0<m<1时,m-1<0,m-2<0,原式=m+1-m+2-m=3-m;当1≤m<2时,m-1≥0,m-2<0,原式=m+m

(m+3m+5m+.+2008m)-(2m+4m+6m+.+2009m)

(m+3m+5m+.+2009m)-(2m+4m+6m+.+2008m)=2009m

2m^2-5m+1/m^2 怎么等于(m^2-5M)+m^2+1/m^2

2m^2-5m+1/m^2中把2m^2=m^2+m^2,移项后就是(m^2-5m)+m^2+1/m^2

(m+3m+5m+...+2009m)-(2m+4m+6m+...2008m)

3m-2m=m5m-4m=m……2009m-2008m=m相当于m+m+m+……m总共2009答案2009m

化简并求值 m*m*m-2m*m+m除以m*m*m-m 其中m=2011

(m^3-2m^2+m)/(m^3-m)=(m^2-2m-1)/(m^2-1)=(m-1)^2/(m-1)(m+1)=(m-1)/(m+1)=2010/2012

(m+1)(m-1)(m-2)(m-4)

解题思路:按照多项式乘以多项式的法则,用多项式的每一项乘以另一个多项式的每一项解题过程:解:(m+1)(m-1)(m-2)(m-4)=(m+1)(m-4)(m-1)(m-2)=(m2-3m-4)(m2

化简 |m|+| (2+m-m^2) 除以(m+1) |

|m|+|(2+m-m^2)除以(m+1)|=|m|+|(m^2-m-2)/(m+1)|=|m|+|(m-2)(m+1)/(m+1)|=|m|+|m-2|(1)当m>=2上式=m+m-2=2m-2(2

化简2[(m-1)m+m(m+1)]乘【(m-1)m-m(m+1))

2[(m-1)m+m(m+1)]×[(m-1)m-m(m+1)]=2(m²-m+m²+m)×(m²-m-m²-m)=2×2m²×(-2m)=-8m&#

m-2m-3m+4m-5m-6m+7m.2004m=?

m-2m-3m+4m-5m-6m+7m.2004m=(1-2-3+4-5-6+7-8-9+...2002-2003-2004)m=(-4-7-10-..-2005)m=-(4+7+10+..+2005

计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m)

(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m)=2010m/2=1005m

(1m+3m+5m+...+2009m)-(2m+4m+6m+...=2008m)

(1m+3m+5m+...+2009m)-(2m+4m+6m+...+2008m)=1m+3m+5m+...+2009m-2m-4m-6m-...-2008m=1m+(3m-2m)+(5m-4m)+.

(m+3m+5m+...+2013m)-(2m+4m+6m+...+2012m)

(m+3m+5m+...+2013m)-(2m+4m+6m+...+2012m)=(2013m-2012m)+(2011m-2010m)+...+(5m-4m)+(3m-2m)+m=m+m+...+m

(m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=?

(m2013m)*1007/2-(2m2012m)*1006/2=1007m

(m+3m+5m+...+2014m)-(2m+4m+6m+...+2013m)

原式=m+3m+5m+.2014m-2m-4m-6m-.2013m=m-2m+3m-4m+5m-6m=m+(3m-2m)+(5m-4m)+(2014m-2013m)=m+m+.1007个m=1007m

(m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)=

=m+(3m-2m)+(5m-4m)+……+(2015m-2014m)=m+1007m=1008m

化简:m+|(1+m^2-2m)/(m-1)|

因为1+m^2-2m=(m-1)^2,因此原式=m+|(m-1)^2/(m-1)|=m+|m-1|,由于m≠1,因此当m>1时,原式=m+m-1=2m-1;当m

化简:2{(m-1)m+m(m+1)}{(m-1)m-m(m+1)}.若m是任意整数.

2{(m-1)m+m(m+1)}{(m-1)m-m(m+1)}.=2(m²-m+m²+m)(m²-m-m²-m)=2*2m²*(-2m)=-8m
