X(M-2)^2-5Y(N-2)^2=5
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^3+N,求M,N
计算(1)(3m-4n)(3m+4n)-(2m-2n)(2m+n) (2)(x+5y)²-(x-5y)
若3x^m+1y^2与x^3y^n的积是单项式3x^5y^5则n^m+m^n=
已知x的m-n的次方*x的2n+1的次方=x的11次方,且y的m-1次方*y的4-n的次方=y的5次方,(m+n)*(m
(x+y)(m+n)2-(x+y)(m+n)2
已知单项式M N满足3x(M-5x)=6x^2y^2 求M N
一道 (已知M,N分别表示不同的单项式,且3x(M-5x)=6x?2y?3+N.求M,N.
3x+4y=-5 5x+6y=-9 (n-8m)x-8y=10 5x+(10m+2n)y=-9 求m.m+n.n=?
若x^3m=4,y^3n=5,求(x^2m)^3+(y^n)^3—x^2m·y^n·x^4m·y^2n的值
已知M=x^2+y^-4X+2y,N=-5 ,M,N的大小
若x^3m=4,y^3n=5,求(x^2m)^3+(y^3n)^2
