(3m^2n^3)/(mn^2)(3m^2n^3)/(mn^2)(3m^2n^3)/(mn^2)(3m^2n^3)/(mn^2)=3m^(2-1)n^(3-2)=3mn原式=3(m^2/m)(n^3/
(3m^2n^3)/(mn^2)
(3m^2n^3)/(mn^2)
(3m^2n^3)/(mn^2)
(3m^2n^3)/(mn^2)
=3m^(2-1)n^(3-2)
=3mn
原式=3(m^2/m)(n^3/n^2)
=3mn
2mn[（2mn）^2-3n（mn+m^2*n）-mn^2]计算
(5mn-2m+3n)+(-7m-7mn)
(5mn-2m+3n)+(-7m-7mn)
2mn[(2mn)²-3n（mn+m²n）-mn²
急2[mn+(-3m)]-3(2n-mn),m+n=2 mn=-3
3(m^2n+mn)-4(mn-2m^2n)+mn.要有过程
1/M+1/N=5 (3M+MN+2N) / (M-MN=3N)
已知m-n=2,mn=1,求多项式(-2mn+2mn+3n)-(3mn+2n-2m)-(m+4n+mn)的值
已知m-n=2,mn=1,求多项式(-2mn+2mn+3n)-(3mn+2n-2m)-(m+4n+mn)的值
已知m+n=3,mn=2/3,求mn-mn+mn的值
已知mn/m+n=2求3m-5mn+3n/-m+3mn-n
已知M+N分之MN=2,求-m+3mn-n分之3m-5mn+3n
已知mn/m+n=2,求3m-5mn+3n/（-m）+3mn-n
已知mn／m+n=2,求3m-5mn+3n/-m+3mn-n的值
m-n=7 mn=-5求(3m+5n+4mn)-(2n-4n+6mn)
(3m^2n^3)/mn)^2
(3m^2n^3)/(mn^2)
计算(-mn)^2×(-m^2n)^3
