3(x^4)^3-2(xy)^4x^8y+5(x^3y^2)x^6y
3(x^4)^3-2(xy)^4x^8y+5(x^3y^2)x^6y
3(x^4)^3-2(xy)^4x^8y+5(x^3y^2)x^6y
无解
3(x^4)^3-2(xy)^4x^8y+5(x^3y^2)x^6y
已知7 x^2 + 5y x^2=12xy,并且xy不等于0,则可求出()的值(1)xy(2)x/y(3)x+y(4)x-y为什么?
(X-3xy+4xy-y)-[-2x-2(xy-3/2xy)-y]+6xy的过程
已知x^2y等于3,求2xy(x^5y^2-3x^3y-4x)
(12x^2y-8xy^2+16xy)/-3x+2y-4=?
(12x^2y-8xy^2+16xy)/-3x+2y-4=?
(5x-4y-3xy)+(8x+y-2xy)合并同类项
3(x-y)²-7(x-y)+8(x-y)²+6(x-y)求详细过程(2) 5xy-4x²y-8xy²+3xy-xy²+4x²y
4X^2-12XY+9Y^2-2X+3Y-6化简!
求(3x^+y^-5xy)-【2x^-(-4xy-y^+7x^)】=?
求(3x^+y^-5xy)-【2x^-(-4xy-y^+7x^)】=?
化简:3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
x²-y²+5x+3y+4(x+y-2xy)(x+y-z)+(xy-1)²
计算:(1)8x^2y^2*(-3x/4y^5) (2)(x+y)^2/xy-y^2*(y-x)^2/xy+y^2
5x^2y-3xy^2+4xy-14xy^2+4xy-2x^2y(化简)
3x^2y^2-[5xy^2-(4xy^2-3)+2x^2y^2,其中x=-3,y=2
3x^2y^2-[5xy^2-(4xy^2-3)+2x^2y^2,其中x=-3,y=2
因式分解 (3x+2y)-(x-y)² x²-xy+3y-3x 2x²+xy-y²-4x+5y-6
