2m/3n×(3n/p)^2÷mn//p^22m/3n×(3n/p)^2÷mn/p^2答案是不是6 3n/2m•(p/3n)²÷p²/mn (-2m/3n)的3次方×(-3n/p)2÷mn/p2 (-2m-3n-p)(2m-3n-p) (m-2n+3p)(m+3n+3p) mn^2/2p^2÷-3m^2n^2/4pq 若(3m+2n)的平方=(3m-2n)的平方+P,则P的值为( ) A.12mn若(3m+2n)的平方=(3m-2n)的平方+P,则P的值为( )A.12mn B.24mn C.6mn D.48mn m^2+n^2+2mn-p^2 （m-2n-p)(m-2n+p)-(m+2n+p)(m+2n+p) 若m、n互为倒数,p、q互为相反数,则2(p+q)的2次方-3mn=________. 已知p与q互为相反数,m与n互为倒数,且m不等于n,求2（p+q）/m-n-【(p+q)-(mn)】/mn的值 已知m,n,p都是整数,且,|m-n|的3次方+|p+m|的五次方=1则|p-m|+|m-n|+2|n-p|= . 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都是整数,且|m-n|+|p-m|=1,求|p-m|+|m-n|+3(n-p)^2的值 （急速）(1)16（p+q)^2-9(p-q)^2 (2)m^5n^5-2n^3m^3+mn 2m²n/3pq²÷5p²q/4mn÷5mnp/3q= 2m²n/3pq²×5p²q/4mn²÷5mnp/3q 已知：mnp=1,m+n+p=2,m^2+n^2+p^2=3,求：分式1/(mn+p-1)+1/(np+m-1)+1/(pm+n-1)的值.
