(-xy^3)^2/(x^2y)^3*x^2y怎么算
(-xy^3)^2/(x^2y)^3*x^2y怎么算
(-xy^3)^2/(x^2y)^3*x^2y怎么算
(-xy^3)^2/(x^2y)^3*x^2y
=x^2y^6/x^6y^3*x^2y
=y^3/x^4 *x^2y
=y^4/x^2
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
(x-2xy)*(-xy+2y*y)-(3x*x-2xy)(x-9xy+6y*y)答案应为-2x-x*x-3x，
2x²y-3(2xy-xy)-xy
因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
化简：3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
计算：3xy[2xy-x（y-2）+x]
计算3xy[2xy-x(y-2)+x-1]
（-3x^y+2xy)-( )=4x^+xy
-xy^2(x+y)^3+x(x+y)^2因式分解
(x+3y)/(x^2+xy)-x+y计算题
X^Y-2XY^2+y^3
x*x+xy=3,xy+y*y=2,则x*x+2xy+y*y=________?
1、(-7x^y)(2x^y-3xy^3+xy) 2、((x-y)^6)/((y-x)^3)/(x-y)
化简：x-y/x+3y÷x^-y^2/x^2+6xy+9y^2-(xy/x+y)
x^2-xy-6y^2+3xy+y+2
[x(x^2y^2-xy)-y(x^2-x^3y)]/3x^2y
[x(x^2y^2-xy)-y(x^2-x^3y)]/3x^2y
[x(x^2y^2-xy)-y(x^2-x^3y)]/(2x^2y)
