(1/4m^2n)(-2mn)(6mn^3)^2
=1/4m^2n*(-2mn)*36m^2n^3
=(-1/4*2*36)m^(2+1+2)n^(1+1+3)
=-18m^5n^5
已知m-n=2,mn=1,求多项式(-2mn+2mn+3n)-(3mn+2n-2m)-(m+4n+mn)的值

m-n=7 mn=-5求(3m+5n+4mn)-(2n-4n+6mn)
计算(-2mn)^3(mn+1/2)(m^2n^2-1/2mn+1/4)
已 知m-n=4,mn=-1,求:(-2mn+2m+3n)-(3mn+2n-2n)-(m+4n+mn)的值
已知m-n=4,mn=-1,求(-2mn+2m+3n)-(3mn+2n-2m)-(m+4n+mn)的值.
若m-n=4,mn=-1,求(-2mn+2m+3n)-(3mn+2n-2m)-(m+4n+mn)
若m-n=4,mn=-1求(9-2mn+2m+3n)-(3mn+2n-2m)-(m+4n+mn)
