(4)2/3X√9x-(x²√1/x-6x√x/4)
|X-1|+|X-2|+|X-3|+|X-4|+|X-5|+|X-6|+|X-7|+|X-8|+|X-9|+|X-10|
已知x=√2+1,求(x²+x-6)/(3-x)×(2x-6)/(x²-4x+4)÷(x+3)
(x+1-1/1-x)÷(x-x²/x-1) (x-4/x-x-6+ x+2/x-3)÷x+1/x-3
化简:[√(x^2-6x+9)/x^2-x-12]*(x^3-16x)/(x^2-3x)-1/(x+3) {x>3}
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
【计算啊 - -】(1/2)x√4x+6x√x/9 - 2x^2√1/x
计算:2x√x-x²√(1/x³)+6x√(x/4)(要过程)
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),
(2x-6)/(x²-4x+4)÷(3-x)/(x²+6x+9)×(2-x)/(x+3)
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
