x*-4x+y*+6y+(根号z-2)+13=0,求(xy)z *为2
x*-4x+y*+6y+(根号z-2)+13=0,求(xy)z *为2
若:X^2-4X+Y+6Y+√ Z-3+13=0求(xy)^z的值
1.已知x,y,z满足2│x-y│+(根号2y-z)+z平方-z+(1/4)=0,求x,y,z值.
已知2X-3Y-Z=0,X+3Y-14Z=0,X,Y,Z不全为0,求【4X的平方-5XY+Z的平方】除以【XY+YZ+Z
已知实数x,y,z满足x²-6xy+10y²+4y+|z²-3z+2|+4=0,求(x+y
已知3x-2y-5z=0,2x-5y+4z=0,且x,y,z都不为0,求(3x*x+y*y+4z*z)/(5x*x+y*
若X的平方-4X+Y的平方+6Y+根号(Z-3)+13=0,求(XY)的Z次方的值
若x-y=6,xy=-8,求代数式(x+y+z)²+(x-y-z)(x-y+z)-2·z(x+y)的值
实数x,y,z满足x=y+根号2,2xy+2*根号2*z*z+1=0,则x+y+z等于多少
已知实数X,Y,Z满足 X²-6XY+10Y²+4Y+∣Z²-3Z+2∣+4=0,求(X+
已知{X-3Y+7z=0,x-2y+4Z (xy不等于0).求X:Y:Z
已知实数x,y,z,满足那么x+y=6,z^2=xy-9,求(x+y)^z
