3x+18-101=x+101

3x+18-101=x+101 3x+18-101=x+101 3x+18-101=x+101 先化简再求值(x+3x+5x+7x+.+101x)-(2x+4x+6x+...100x),其中x=51分之2 x-4x/3(101-x) 解方程3x+18-101=x+101 怎么解3X+18-101=X+101 3x+18-101=x+101怎么解啊 (3x+18)-101=x+101怎么解, 3x+18-101=x+101 这个怎么算 解方程【3x+18-101=x-101】错了，是3x+18-101=x+101 3x+18=x+101怎么解? 3x+18-101=+1013x+18-101=x+101 1/(x+1)(x+2)+1/(x+2)(x+3)+1/(x+3)(x+4)+...+1/(x+100)(x+101) x+(x+3)+2x+(2x-18)=255 计算1/[x(x+3)]+1/[(x+3)(x+6)]+.+1/[(x+15)(x+18)]=? 求函数f(x)=x(x-1)(x-2)……(x-100)在x=0处的导数值,f(x)=x^101+(a1)x^100+(a2)x^99+……+(a99)x^2+(a100)x所以f(x)在x=0处的导数值为a100也就是f(x)中x的系数而f(x)=x(x-1)(x-2)……(x-100)所以此系数为(-1)×(-2)×(-3)×(-4) 高数题求解答过程f(x)=x(x-1)(x+2)(x-3)(x+4).(x+100)求f'(1)要过程,答案我有是-101!/100
