求满足2p*p+p+8=m*m-2m的所有素数p和正整数m
若实数m,n,p满足m-n=8,mn+p^2+16=0,求m+n+p的值
证明:当n>1时,不存在奇素数p和正整数m使p^n+1=2^m;当n>2时,不存在奇素数p和正整数
已知m,n.p都是整数,且|m-n|^3+|p-m|^5=1,求|p-m|+|m-n|+2|n-p|的值
已知m、n、p满足|2m|+m=0,|n|=n,p|p|=1.化简：|n|-|m-p-1|+|p+n|-|2n+1|.
证明：m^p+n^p恒等于0(mod p),则m^p+n^p恒等于0(mod p^2),p为奇素数
一道初一代数化简题,已知m,n,p满足|2m|+n=0.|n|=n,p+|p|=1,化简|n|-|m-p-1|+|p+n
已知M={1,2,3,4,5,6,7,8,9},集合P满足:P是M的子集
求助：证明对任意素数p,存在正整数前n项和Sn及前m项和Sm(n,m为正整数),p=Sn/Sm
急求p乘以2+m-p的最大值,
1.有4个不同的正整数,m、n、p、q满足（7-m)(7-n)(7-p)(7-q)=4,则m+n+p+q=?
已知集合 M,P 满足 M∪P=M 则 P是M的真子集.为什么?
