5（x^3·y^2)^2/(5x^2)^3 等于多少?
5（x^3·y^2)^2/(5x^2)^3 等于多少?
5（x^3·y^2)^2/(5x^2)^3 等于多少?
原式 = 5 * (x^3)^2 * (y^2)^2 / [5^3 * (x^2)^3]
= (5 * x^6 * y^4) / (125 * x^6)
= y^4 / 25
5（x^3·y^2)^2/(5x^2)^3=5*X^6Y^4/125X^6=Y^4/25
(5x^6y^4)/(5^3x^6)=y^4 /25
化简:5(x-y)+2(x+y)-3(x-y)
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
(2x+y)²+(x+3y)(x-3y)-x(5x+8y)因式分解
(2x-3y)-(5x-y)
(2X-3y)-(5x-y)
(2x-5y)(3x+y)
因式分解(x-2y)(x-3y)+(x-4y)(x-5y)+（x-3y)(x-5y)+(x-2y)(x-4y)
[(x+2y)(x-2y)-(2x-y)^2+(3x-y))2x-5y)]/(-x)我急用
[(x+2y)(x-2y)-(2x-y)²+(3x-y(2x-5y)]/(-x)的解答
[2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2
(5x+2y)(5x-2y)-(3x+2y)(3x-2y)
2(2x+3y)(3x+2y)-(6x-y)(2x-5y)
化简：[(x+2y)^2-(x+y)(3x-y)-5y^2]/2x
(2x -y)(3x-2y)+(y-x)(2x-5y)
(2x-y)(3x-2y)+(y-x)(2x+5y)
x+y/2+x-y/6=5 2(x+y)-3(x-y)=-2
(2x-y)(3x-4y)-2(x-y)(2x-5y)简便运算
5/4(x+y)(-x-y)^3*[-4/3(x-y)]*[-3/5(y-x)^2]
