已知单项式M.N满足等式3x(M-5x)=6x2y3+N,则M=
已知:单项式M,N满足2x(M+3x)=6x的2次方y的2次方+N,求M,N

由于2x(M+3x)=6x^2y^2+N,所以2xM+6x^2=6x^2y^2+N比较可知2xM=6x^2y^2,6x^2=N所以M=3xy^2,N=6x^2

已知单项式M,N满足3x(M-5x)=6x²y²+N,求MN.

∵M、N都是单项式∴3xM也是单项式∵3xM-15x^2=6x^2y^2+N又∵-15x^2≠6x^2y^2∴3xM=6x^2y^2,N=-15x^2

已知单项式M,N满足3x(M-5x)=6x²y+N,则M= N=

展开,移项,得3xM-N=6x²y+15x²则M=2xyN=-15x²或者M=5xN=-6x²y

已知,单项式M,N满足2x(M+3x)=6x²y²+N,求M,N

2x(M+3x)=6x²y²+N2xM+6x²=6x²y²+N所以N=6x²,且2xM=6x²y²,即M=3xy&sup

已知单项式M,N满足等式3x(M-5x)=6x平方y3次方+n,则M= ,N=

晕,题目的式子打开3xM+(-15x^2)=6x^2y^3+N所以M=6x^2y^3/(3x)=2xy^3N=-15x^2

已知单项式M,N满足等式3x(M-5x)=6x平方y3次方+n,求MN

3x(M-5x)=3xM-15x²=6x²y³+n3xM=6x²y³-15x²=NM=2xy³MN=-30x³y

已知,单项式M,N满足2x(M+3x)=6x^2y^2+N,求M,N.

解析2*(M+3x)=2*m+6x=6x²y²+N两边比较2*m=6x²y²m=3x²y²N=6x再问:我没看明白。请问这几个算式都是为什么

若单项式M,N满足等式3x(M-5x)=6x的二次方y的三次方+N则M-N为___

原式展开后是3xM-15x^2=6x^2*y^3+N对比一下可以知道N=-15x^2M=2x*y^3所以M-N=2x*y^3+15x^2

已知 ,单项式M,N满足等式2x﹙M-x﹚=6x²y³+Nx²,求M,N

由题意得2xM-2x^2=6x^2y^3+Nx^2∴N=-2M=3xy^3很高兴为您解答,【学习宝典】团队为您答题.请点击下面的【选为满意回答】按钮,

已知单项式M,N满足3x(M-5x)=6x^2y^3+N,求M,N

3x(M-5x)=6x^2y^3+N,3x*M-15x^2=6x^2y^3+NM=2xy^3N=-15x^2

已知单项式M,N满足3x*(M-5x的二次方)=6x平方*y平方+N

M*N=-30X⁴Y²再问:请问对应厢相等是公式么再答:不是公式这里等号前面等于等号后面由于-15x³≠6x²y²所以只能是3Mx=6x²

已知单项式M,N,满足3x(M-5x)=6xy,+N,则M= ,N=

M=2yN=-15x^2再问:可以发过程吗再答:前面有点写错了,少看了个平方再问:就是咯,再答:

已知单项式M、N满足2x(M+3x)=6x^2y^2+N,求M、N.

由于2x(M+3x)=6x^2y^2+N,所以2xM+6x^2=6x^2y^2+N比较可知2xM=6x^2y^2,6x^2=N所以M=3xy^2,N=6x^2

已知单项式M、N满足2x(M+3x)=6x^2y^2+N,求MN

2x(M+3x)=6x²y²+N2Mx+6x²=6x²y²+N∴2Mx=6x²y²N=6x²即:M=3xy²N

已知单项式M,N满足等式3x(M-5x)=6x^2y^3+N.求M,N.

M=2xy^3,N=-15x^2左边展开为两个单项式相加3x*M-15x^2=6x^2y^3+N一一对应可得3x*M=6x^2y^3-15x^2=N

已知单项式(m-2)x^3y^n-3是一个关于字母x,y的五次单项式,则m,n满足的条件是

(m-2)x^3y^(n-3)是一个关于字母x,y的5次单项式则有:3+(n-3)=5m-2≠0n=5m≠2

已知单项式M、N满足等式:2x(M-x)=6x²y三次方+Nx²,求M、N.

2x(M-x)=6x²y³+Nx²,2Mx-2x²=6x²y³+Nx²,2Mx=6x²y³,M=3xy&sup

已知单项式M、N满足等式:2x(M-x)=6x的平方y的三次方+Nx的平方,求M+N

2x(M-x)=2x*M-2*x^2=6x的平方y的三次方+Nx^2所以2x*M=6x^2*y^3,-2*x^2=Nx^2M=3xy^3,N=-2M+N=3xy^3-2
