已知XX+YY+4X-6Y+13=0,则X的Y次方是已知XX+YY+4X-6Y+13=0,则X的Y次方是已知XX+YY+4X-6Y+13=0,则X的Y次方是XX+YY+4X-6Y+13=0(X+2)&
已知XX+YY+4X-6Y+13=0,则X的Y次方是
已知XX+YY+4X-6Y+13=0,则X的Y次方是
已知XX+YY+4X-6Y+13=0,则X的Y次方是
XX+YY+4X-6Y+13=0
(X+2)²+(Y-3)²=0
X+2=0 Y-3=0
X=-2 Y=3
X的Y次方=-8
可以先配方,原式可写成x2+4x+4+y2-6y+9=0,(x+2)^2+(y-3)^2=0,解得x=-2,y=3,所以x^y=-8
-8
-8
已知xx+yy+4x-6y+13=0,求(xx-2x)/xx+3yy的值.
已知XX+YY+4X-6Y+13=0,则X的Y次方是
已知xx+yy-4x-6y+13=0求3x+4y的值
已知2x=3y,求xy/xx+yy-yy/xx-yy的值
xx+2x+yy+6y+10=0求xx+yy的值
已知实数x,y满足xx+yy-2x=0,则2xx+yy的取值范围是why
若(xx)+(yy)-4x+6y+13=0,求2x+3y的值?
已知xx yy 2x-6y 10=0求x,y的值已知xx+yy+2x-6y+10=0求x,y的值
若xx+yy-2x-6y+10=0,求分式(xx-yy)/xy的值.
(x-y)(x+y)(xx-yy)=?
若xx-2x+yy+6y+10=0 求xx-yyy的值
若xx-2x+yy+6y+10=0 求xx-yyy的值
已知x(x-1)-(xx-y)=-3求xx+yy-2xy
已知x(x+1)-(xx+y)=3,求(xx+yy)/2-xy的值
已知xx+xy=1,xy-yy=-4,则xx+2xy-yy=
已知:xx-xy=7,xy-yy=4,则xx-yy=( )
x-y/x+y=2,则xx+2xy+yy/4xy=?
已知:xx+yy-8x+12y+52=0,求:x/y-y/x=多少
