x^3+10x^2+25x+15=
已知 X=4- 根号3 求 (X*X*X*X-6X*X*X-2X*X+18X+23) / (X*X-8X+15)的值
1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550
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),
x-2x+3x-4x+...+99x-100x=25
x的平方-2x+1=15 ; x(2x-5)=4x-10 ; x的平方+5x+7=3x=11
(x+5)²-(x-2)(x-3) =x²+10x+25-(x²-5x+6) *5x怎么来
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
1x()+2x()+3x()+4x()+5x()+6x()+7x()+8x()加9x()+10x()=1980
1X?+2X?+3X?+4X?+5X?+6X?+7X?+8X?+9X?+10X?=1980求?是多少
C语言中编写s=1-x+(x*x)/2!-(x*x*x)/3!+(x*x*x*x)/4!知道最后一项的绝对值小于10的-
|X-1|+|X-2|+|X-3|+|X-4|+|X-5|+|X-6|+|X-7|+|X-8|+|X-9|+|X-10|
