4m^2n^3/(-6mn)
=(-2/3)mn²
4m^2n^3/(-6mn)求解!帮帮忙!
(7m²-4mn-n²)-(3m²-mn+2n²)求解
m-n=7 mn=-5求(3m+5n+4mn)-(2n-4n+6mn)
急需求解!已知:m^2+n^2=6,则代数式(3m^2-4n^2-mn)-(4m^2-3n^2-mn)的值是_______.
先化简,再求值(3M-5M+4MN)-(2M-4N+6MN)
3(m^2n+mn)-4(mn-2m^2n)+mn.要有过程
计算:[-m^3n/(m-n)^2]^4*[(n^2-mn)/m]^3/m^4n^10*[(mn-n^2)/m]^6
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
(3m-5n+4mn)-(2m-4n+6mn)其中m-n=7,mn=-5
(3m-5n+4mn)-(2m-4n+6mn) mn=-5 m-n=7快帮我打答吧!谢谢了!
若m-n=7,mn=-5,求(3m-5n+4mn)-(2m-4n+6mn)的值.
若m-n=7,mn=5求(3m-5n+4mn)-(2m-4n+6mn)要计算过程]
若M-N=7,MN=-5,求(3M-5N+4MN)-(2M-4N+6MN)的值
已知m-n=7,mn=-5,n=?根据m-n=7,mn=-5,求{3m-5n+4mn}-{2m-4n=6mn}的值
已知m-n=4,mn=2,求多项式(-2mn+2m+3n)-(3mn+2n-2n)-(m+4n+mn)的值
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=2,求多项式(-2mn+2m+3n)-(3mn+2n-2m)-(m+4n+mn)的值.
