刚刚学,不是很懂,x-17.6=984x=9.696-x=8.9x除8=440如:5+X=71.5X+5-5=71.5-

用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
(x+12)(x-2)+(x+7)(x+8)-(x+5)(x-10),其中x=2
(X+X)+(X-X)+(X*X)+(X/X)=100
x-4/x-5 - x-5/x-6=x-7/x-8 - x-8/x-9求x=?
X-5+8*X=7*X-2*X-1
y=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10)的导数在x=1
设函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10),
已知1+x+x^2+x^3=0,求x+x^2+x^3+x^4+x^5+x^6+x^7+x^8的值
2x+3x+4x+5x+x+6x+7x=100
