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+1y^2与x^3y^n的积是单项式3x^5y^5则n^m+m^n=若3x^m+1y^2与x^3y^n的积是单项

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+1y^2与x^3y^n的积是单项式3x^5y^5则n^m+m^n=

若3x^m+1y^2与x^3y^n的积是单项式3x^5y^5则n^m+m^n=
.3x^m+1y^2与x^3y^n的积是3x^(m+4)y^(2+n),即是 单项式3x^5y^5
则有m+4=5,n+2=5
m=1,n=3
n^m+m^n=1+3=4
