解答如下:
x²+y²+4x-6y+13=0
(x + 2)² + (y - 3)² = 0
所以x = -2,y = 3
所以x的y次方为-8
解:原方程可化为:(x+2)^2+(y-3)^2=0
所以,可得:x=-2,y=3
所以,x的y次方=(-2)^3=-8
x²+y²+4x-6y+13=0
(x²+4x+4)+(y²-6y+9)=0
(x+2)²+(y-3)²=0
x+2=0, y-3=0
x=-2, y=3
x^y=(-2)³=-8
x²+y²+4x-6y+13=0
(x+2)²+(y-3)²=0
x+2=0 x=-2
y-3=0 y=3
x^y=(-2)³=-8
x^2+y^2+4x-6y+13
=x^2+4x+4+y^2-6y+9
=(x+2)^2+(y-3)^2=0
所以x+2=0 y-3=0
即x=-2 y=3
所以x^y=(-2)^3=-8
