x^2+2x+y^2-8y+17=0,求x^yx^2+2x+y^2-8y+17=0,求x^yx^2+2x+y^2-8y+17=0,求x^yx^2+2x+y^2-8y+17=0(x+1)^2+(y-4)

x^2+2x+y^2-8y+17=0,求x^y
x^2+2x+y^2-8y+17=0,求x^y

x^2+2x+y^2-8y+17=0,求x^y
x^2+2x+y^2-8y+17=0
(x+1)^2+(y-4)^2=0
∴x=-1,y=4
x^y=(-1)^4=1

(x²+2x+1)+(y²-8y+16)=0
(x+1(²+(y-4)²=0
所以x+1=y-4=0
x=-1,y=4
所以x的y次方=1

x^2+2x+y^2-8y+17=0
(x^2+2x+1)+(y^2-8y+16)=0
(x+1)^2+(y-4)^2=0
x=-1, y=4
x^y=(-1)^4=1
