|m-2|十(n+1)^2=0,则mx^n+3y^2/5的系数为|m-2|十(n+1)^2=0,则mx^n+3y|m-2|十(n+1)^2=0,则mx^n+3y^2/5的系数为|m-2|十(n+1)^

|m-2|十(n+1)^2=0,则mx^n+3y^2/5的系数为|m-2|十(n+1)^2=0,则mx^n+3y
|m-2|十(n+1)^2=0,则mx^n+3y^2/5的系数为
|m-2|十(n+1)^2=0,则mx^n+3y

|m-2|十(n+1)^2=0,则mx^n+3y^2/5的系数为|m-2|十(n+1)^2=0,则mx^n+3y
|m-2|十(n+1)^2=0

m-2=0
n+1=0

m=2
n=-1

mx^n+3y为 x分之2+3y

m=2 n=-1代入就好啦

m-2=0,n+1=0
m=2,n=-1
系数=m/5=2/5
