已知m>4 化简|m-4|+|7-2m|
已知m>4 化简|m-4|+|7-2m|
已知m>4 化简|m-4|+|7-2m|
|m-4|+|7-2m|
=m-4+(2m-7)
=3m-11
“yzwb我爱我家”很高兴与您共同探讨该问题.
|m-4|+|7-2m|=m-4+2m-7=3m-11
原式=m-4+2m-7=3m-11
已知m>4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
已知m>4 化简|m-4|+|7-2m|
已知m>4,化简:|m-4|+|7-2m|+|m^2-2m+1|-|m^2-2m-3|
m-2m-3m+4m-5m-6m+7m.2004m=?
化简(m*m-2m)/(4-m*m)
m-2m-3m+4m-5m-6m+7m-8m-9m+...+2002m-2003m-2004m求m的值
计算(m+3m+5m+7m+.+2009m)-(2m+4m+6m+.+2008m)
计算(m+3m+5m+7m+.+2013m)-(2m+4m+6m+.+2012m)
(m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=?
(m+3m+5m+7m+.+2011m)-(2m+4m+6m+.+2010m) 要说理由!
计算:m-2m-3m+4m-5m-6m+7m-8m-9m+...+2002m-2003m-2004m
m-2m-3m+4m-5m-6m+7m-8m-9m+.+2002m-2003m-2004m
已知2^m=a,化简16×2^2m-1 ×2^3m-1 -4^m ×8^m
已知2^m=a,化简16×2^2m-1 ×2^3m-1 -4^m ×8^m
已知-3<m<2.化简|m-2|+|m+3|-|3m+9|-|2m-4|
已知m^2+m-1=0,那么m^4+2m^3-m-2009=
已知m+1/m=3,计算(m^4+m^2+1)/m^2的值
化简:【2m/(m+2) - m/(m-2)】÷m/(m²-4)
