(3m+n-p)(3m-n+p)(3m+n-p)(3m-n+p)(3m+n-p)(3m-n+p)(3m+n-p)(3m-n+p)=[3m+(n-p)][3m-(n-p)]=(3m)²-(n-
(3m+n-p)(3m-n+p)
(3m+n-p)(3m-n+p)
(3m+n-p)(3m-n+p)
(3m+n-p)(3m-n+p)
=[3m+(n-p)][3m-(n-p)]
=(3m)²-(n-p)²
=9m²-(n²-2np+p²)
=9m²-n²+2np-p²
(m-2n+3p)(m+3n+3p)
(3m-n-p)(3m+n-P)
(3m+n-p)(3m-n+p)
计算(-3m+n-p)(3m-n-p)
(-2m-3n-p)(2m-3n-p)
计算 (-3m+n-p)(3m-n-p)是不是[-p-(3m+n)][-p+(3m-n)]?
[(n-m)^3]^p.[(m+n)(m-n)^p]^5p为奇数时等于 急
计算:[(n-m)^3]^p*[(m-n)*(n-m)^p]^4 快!
[(m-n)^3]^p*[(m-n)(m-n)^p]^5急用
