若2y^m+5*x^n+3与-3x^2y^3是同类项,则m^n=?急需求答案!

若3x^m+1y^2与x^3y^n的积是单项式3x^5y^5则n^m+m^n= 若3x^(m+5)y^2与x^3y^n是单项式,则m^n=_____ 若3x^(m+5)y^2与x^2y^n的和是单项式,则n^m= 若3x^(m+5)y^2与x^3y^n是单项式,则m^n=_____ 为什么x^ m+5与x^ 3相等 2m+n 5 3 2m-n诺4x y 与x y 是同类项,m/n= 若2x^m-n+1y^3m-2n-5与-3x^n-1y是同类项,则m=___,n=____RT 若单项式mx^n+1y^2m+5与x^3y的和为单项式m-n= 若[-3(x+y)^m*(x-y)^2n]^2*[-(x+y)^2]=-a(x+y)^10*(x-y)^12-n,求m,n的值 若代数式2x^2 y^m与-1/3x^n y^3是同类项,则m+n= 若2x^3y^m与-3y^2x^n是同类项,则m+n= 若y=3x+m与y=nx-2互为反函数,求m n 若y=3x+m与y=nx-2互为反函数,求m,n 若-7x^m+2y与-3x^3y^n是同类项,则M= N= 3x^m+5y^2与x^3y^n的和是单项式,则n^m= 3x^m+5y^2与x^3y^n的和是单项式,求m,n各是几? 3x^(m-5)y^2与x^3y^n的和是单项式.则m^n=? 若-2x^2*y(-x^m*y+3xy^3)=2x^5y^2-6x^3y^n,求m,n的值? 因式分解 (m+n)(x-y)-(m+n)(x+y) (x-2y)(2x+3y)-2(2y-x)(5x-y) 2道因式分解 （m+n)(x-y)-(m+n)(x+y) (x-2y)(2x+3y)-2(2y-x)(5x-y)
