X=5m/2+3n Y=5m/3+2n X:Y=3:2 求m:n

已知单项式M,N满足3x(M-5x)=6x^2y^3+N,求M,N 集合M={X=3m+1,m∈N*},N={y/y=5n+2,n∈N*},则M∩N=? 已知单项式M N满足3x(M-5x)=6x^2y^2 求M N 已知,单项式M,N满足2x(M+3x)=6x^2y^2+N,求M,N. 已知单项式M、N满足2x(M+3x)=6x^2y^2+N,求M、N. 已知,单项式M,N满足2x（M+3x)=6x²y²+N,求M,N 若x^3m=4,y^3n=5,求（x^2m)^3+(y^3n)^2 若x^3m=4,y^3n=5,求（x^2m)^3+(y^n)^3—x^2m·y^n·x^4m·y^2n的值 3x+4y=-5 5x+6y=-9 (n-8m)x-8y=10 5x+(10m+2n)y=-9 求m.m+n.n=? X=5m/2+3n Y=5m/3+2n X:Y=3:2 求m:n 计算：1.[(m+n)(n-m)-(m+n)^2+3m(m+n)]除以（-2M),其中m=-4,n=2 2.(x+y)( 当m、n为何数时,函数y=(5m-3)x的2-n次方+(m+n)
