[10(8-x)+x]*[10x+(8-x)]=1855 怎么展开
[10x+(8-x)][(8-x)*10+x]=1855
10^x=8 x怎么算?
(x+x+10+x+8)×3=36怎么解?
(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
将y=(x^3-2x)/(x^2+x-2)展开成x+1的幂级数怎么展开?
解方程.(5x/x²+x-6)+(2x-5/x²-x-12)=7x-10/x²-6x+8
怎么解8x=10(x-1.5*2)
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+7/x+6)+ (x+9/+x+8)=(x+10/x+9)+(x+6/x+5)
1.x+9/x+8- x+10/x+9=x+6/x+5- x+7/x+6;
