{x+10}x{x+10}=0.25x
(x+12)(x-2)+(x+7)(x+8)-(x+5)(x-10),其中x=2
解方程(x/x(x+2))+(x/(x+2)(x+4))+.+x/(x+8)(x+10)=1
10x-3.14*x*x*0.25=3.14*x*x*0.75 怎么算
(X+X)+(X-X)+(X*X)+(X/X)=100
x+2x×10=10x+2x+36
[10x+(8-x)][(8-x)*10+x]=1855
X/15 + X/12 + X/10 = 1365,求X,
x=10; while (x) x-- 中while(x)是什么意思?
三分之一X+四分之一X+三分之一X-10=X
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*10=x-59.94
