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

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= 2m+n 5 3 2m-n诺4x y 与x y 是同类项,m/n= 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 若2x^m-n+1y^3m-2n-5与-3x^n-1y是同类项,则m=___,n=____RT 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-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=? 2x^2m-n y^3m-2n 与5x^2n y^5是同类项,则m= ,n= 若x^2y^n-1与-1/2x^m+1y^3是同类项,则+n= 若单项式-4x^m-1 y^n+1与2/3x^2m-3 y^3n-5是同类项,则m=( ),n=若单项式-4x^m-1 y^n+1与2/3x^2m-3 y^3n-5是同类项,则m=( ),n=( ) 若-2X^my^6与3/5x^3y^2n是同类项,则m^n= 若2X^3Y^N与-5x^my^2是同类项,则m=?n=? 若-3/5X~mY~n与2X~4Y~2是同类项,那么m=------n=------
