(x+10)+(X+8)+X\3=36
(x+10)+(X+8)+X\3=36
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
解方程.(5x/x²+x-6)+(2x-5/x²-x-12)=7x-10/x²-6x+8
解方程1/x(x+1)+1/(x+1)(x+2)+...+1/(x+8)(x+9)=2x+3/x(x+9)
解方程:1\x(x+1)+1\(x+1)(x+2)+.+1/(x+8)(x+9)=2x+3\x(x+9)
3X+(X+2)+(X+1)*(X-1)=4*(X²+8)
(X-X*20%-18-(X-X*20%-18)*10%=X*1/2-3(过程)
(x+x+10+x+8)×3=36怎么解?
f(x)=x²+3x|x-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),
