x^-2、y^-2、x^-2/3、y^-2/3分别为:x的-2次方、y的-2次方、x的-2/3次方、y的-2/3次方
(x^-2+y^-2)/(x^-2/3+y^-2/3)-(x^-2-y^-2)/(x^-2/3-y^-2/3)x^-2、y^-2、x^-2/3、y^-2/3分别为:x的-2次方、y的-2次方、x的-2/3次方、y的-2/3次方
其实很简单的,数学不能怕麻烦,你把分子分母同时乘以想(x*y)^5(xy的5次方)再进行运算,最后结果是2*(xy)^5*(y^3-x^3)/y^10-x^10
2(x-y)²-3(x-y)(-y-x)
x(x-y)2-(y-x)3
[2/3x-2/x+y(x+y/3x-x-y)]/x-y/x
化简:{2/3x-2/(x+y)[(x+y)/3x-x-y]}/(x+y)/x
计算2/3x-2/x+y(x+y/3x-x-y)/x-y/x
化简3x-2/(x+y)[(x+y)/3x-x-y]÷(x-y)/x
计算(x-y)^2×(x-y)^3×(y-x)×(y-x)^2
(x+y)/2- x-y/2=6 3(x+y)=4(x-y)
(y-x)^4(x-y)^3+2(x-y)^6(y-x)
(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
12(x+y)^3(y-x)/【4(x+y)^2(x-y)】
2分之x+y+3分之x-y;4(x+y)-(x-y)谢谢了,
3x(x-2y)+(x+2y)(2x-y)-3y(y-2x)
2(x-y)+3(x+y)2-5(x-y)-8(x+y)2-(x-y)
(x-y)(x-y)2(y-x) (x+2y-?)(x-2y+?)
计算:x+2y/x-y+2x/y-x-3y/x-y
化简:(x-3y)(x+y)-(x-2y)(x+2y)-(x-y)平方
