7m(4mp)÷7m
m-2m-3m+4m-5m-6m+7m.2004m=?
如果(m-p)整除(mn-pq),那么(m-p)整除(mp-nq)
已知M(4,0),N(1,0),若动点P满足向量MN×向量MP=6向量NP
(3+m)(3-m)+m(m-4)-7 其中m等于四分之一
(m+3m5m+7m+.2009m)-(2m+4m+6m.2008m)
已知m>4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
(m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=?
(m+3m+5m+7m+.+2011m)-(2m+4m+6m+.+2010m) 要说理由!
m-2m-3m+4m-5m-6m+7m-8m-9m+.+2002m-2003m-2004m
在平面直角坐标系xoy中,x轴上的动点M(x,0)到定点P(3,4)、Q(1,2)的距离分别为MP和MQ,当MP+MQ最
2m/5n^2p-3n/4mp^2
计算2m/5n²p-3n/4mp²
