x≥0
所以|x|=x
原式=√[(4x²)(3y+6y³)]
=√[(2x)²(3y+6y³)]
=|2x|√(3y+6y³)
=2x√(3y+6y³)
所以|x|=x
原式=√[(4x²)(3y+6y³)]
=√[(2x)²(3y+6y³)]
=|2x|√(3y+6y³)
=2x√(3y+6y³)
将(√x-y)/(x-y)÷√(xy/x³-x²y)(x>y>0)化简
求因式分解(x-y)²-2(x-y)³和(x+y)(x-y)-x(x-y)
2.(x+y)²(x-y)²-(x-y)(x+y)(x²+y²)
若|x+2y-1|+y²+4y+4=0,求(2x-y)²-2(2x-y)(x+2y)+(x+2y)&
已知4x²+y²-4x-6y+10=0求(2/3x(√9x)+(y²√x/y³)
因式分解 -5x³y(x-y)³+20y【x²(y-x)】²
已知x²+y²-8x+6y+25=0,求(x-y+4xy/x-y)(x+y-4xy/x+y)
(x-y)³(y-x)(y-x)²+(x-y)^6
(x-y)的四次方(x-y)-2(x-y)²(y-x)³等于?
若|x+y-1|+(x-y-2)²=0,求代数式(x+2y)(x-2y)-(2x-y)(-y-2x)的值.
已知平面曲线Ω={(x,y)|y≥0 y≤√4-x²﹜...
已知(√x-y-4)+|x-2y-5|=0,则√x+y²=____.³√x²-y²
