(x^2·x^m)^3/x^2m

(x^2·x^m)^3/x^2m |x-2|-|x-m| 2x-3m 计算:(x^m+n)^2·(-x^m-n)^3+x^3m-n`(-x^3)^m (x^2*x^m)^3/x^2m x^(3)*x^(2m +1)*x^(m)=x^(31) 求m的值 m x平方-2x-m+1 因式分解(m-1)x-(x^2-m) 4^x+2^x-m 计算x^3m/(x^m-1)-x^2m/(x^m+1)-1/(x^m-1)+1(x^m+1) 计算：（1)x*x^m-1+x^2*x^m-2-3*x^3*x^m-3 x>2m+3 ,0.5x 多项式x^2m-x^m提取公因式x^m后,另一个因式是?我的解题思路是x^2m-x^m=x^m·x^2-x^m·1=x^m(x^2-1)=x^m(x+1)(x-1)所以 另一个因式是(x+1)(x-1)但是答案上写的是x^m-1 (1-m)x^2+(m-3)x+2 十字相乘 4m(x-y)-2m^2(y-x)^3 (8x^2m-3-6x^m+2-4x^m)/(-2x^m-3)等于多少这是个计算 分式的乘除计算:(1)m/m²-1·m²+m/m²；(2)x-2/3-x·x²-6x+9/x²-4；(3)3x-6/x²-4÷x+2/x²+4x+4；(4)x²-2x+1/x²-1÷x-1/x²+x. 把下列各式分解因式：(m+4)(m-2)+9; (x+3m)(x-3M)-x+3m
