若|2x-3|+(3y-2)^2=0,则(xy-2)^2013的值等于________?若|2x-3|+(3y-2)^2=0,则(xy-2)^2013的值等于________?若|2x-3|+(3y-
若|2x-3|+(3y-2)^2=0,则(xy-2)^2013的值等于________?
若|2x-3|+(3y-2)^2=0,则(xy-2)^2013的值等于________?
若|2x-3|+(3y-2)^2=0,则(xy-2)^2013的值等于________?
|2x-3|+(3y-2)^2=0,两个非负数的和为0 那么他们都等于0
所以 2x-3=0 3y-2=0
解得x=3/2 y=2/3
xy=1
(xy-2)^2013
=(1-2)^2013
=(-1)^2013
=-1
因为|2x-3|不小于0,(3Y-2)^2不小于0,
所以|2x-3|等于0,(3Y-2)^2等于0。
X=1.5,Y=2/3
XY-2=-1
(xy-2)^2013=(-1)^2013=-1
若3x-5y=0,则x+y/x=(),x-y/y=(),2x-3y/2x+3y=( )
若(x-y)/(x+y)=3 则(x+2y)/(6x-7y)等于
若x-y不等于0,2x-3y=0,则分式(10x-11y)/(x-y)的值是()?(10x-11y)/(x-y) =[(8x-8y)+(2x-3y)]/(x-y) =8为什么8X-8Y=8?(10x-11y)/(x-y)=[(8x-8y)+(2x-3y)]/(x-y)=8+(2x-3y)]/(x-y)=8+0=8
(5)若x/2=y/3(y不为0)则x/y=____,x+y/y=___,y/x-y=___.
若2x=3y,则(x*x+y*y)/x*x=?
若x,y满足|2x-y-3|+|3x+2y+1|=0,则x= y=
若线段x ,y 满足[2x-3y]*[3x+2y]=0 则x/y=?
若x,y满足|x-y+1|+(x+y+3)^2=0则x^2-y^2=
若|x+y-3|+(x-y-5)^2=0,则x)^2-y^2=
若|x|=2,|y|=3,且y/2+x《0则x+y
若[x-y+3]+|2x+y|=0,则x+y=?
若3x-2y=0,则X+y/x-y等于多少?
若2x-3y+4=0则x(x*x-1)+x(5-x*x)-6y+7
若|2x-y+5|+(x+2y-4)的平方=0,则(2x-y)的三次方-(x-3y)(y-2x)的平方
若|x-3|+(y+2)=0,则(x-y+4xy/x-y)(x+y-4xy/x+y)的值是
若|x-3|+(y+2)²=0,则(x-y+4xy/x-y)(x+y-4xy/x+y)的值是
若x+2y分之x-y=3,则代数式x+2y分之2(x-y)-3(x-y)分之x+2y的值为
若y=x(x-1)(x-2)(x-3),则y′(0)=
