(X^3Y^2)^3+(-2X^3Y^3)^2×X^3
3(x^4)^3-2(xy)^4x^8y+5(x^3y^2)x^6y
已知x^2y等于3,求2xy(x^5y^2-3x^3y-4x)
因式分解-1/4x^3+x^2y-x^2y
(X^3Y^2)^3+(-2X^3Y^3)^2×X^3
已知y=根号x-2+根号2-x+3,求y^x的平方根
把多项式X^2-Y^2-2X-4Y-3因式分解
化简:5根号X^3Y-2Y根号XY-6根号XY+根号X分之Y+根号Y分之X
根号(2X-Y)^2=3,三次根号(X-2Y)^3=-3,求(X+2Y)/(X-Y)
分解因式:2m^3 - 8m(x+2)(x+4)+ x^2 -44(x-y)^2 - 2(y-x)^3x^2 (y^2
分解因式:2m^3 - 8m (x+2)(x+4)+ x^2 -4 4(x-y)^2 - 2(y-x)^3 x^2 (y
求导数y=(x^2+2x)^3
