2/3根号9x+6根号x/4-2x根号1/x
2/3根号(9x)+6根号(x/4)-2x根号(1/x)..要过程!
5/2根号4x-6根号x/9+3x根号1/x
化简 2/3X*根号9X-(X^2*根号1/X立方)+(6X*根号X/4)
2/3X根号9X+X平方根号1/X立方-6X根号X/4的值
已知根号(3x+1)(2-x)=根号3x+1*根号2-x化简|x-4|+根号9x^2+6x+1+|x-2|
4x-y/2根号x+根号y 9x-6根号xy+y/3根号x-根号y
计算:(2/3x根号下9x+6x根号下y/x)+(y根号下x/y-x的平方根号下1/x)=
计算:(2/3x根号下9x+6x根号下y/x)+(y根号下x/y-x的平方根号下1/x)=
化简:(1/2根号x^3)+(6x根号x/9)-(4x^2根号1/x)
当x>3时,化简(3-x)根号2x/9-6x+x²
化简2/3x•根号9x-x^2•根号1/x^3+6x•根号x/4,x=5
三分之二根号9x+6根号4分之x-3x根号x分之1
{6根号4分之x-2x根号x分之1}除以3根号x
(6根号x/4-2x根号1/x)÷3根号x
(根号x-1)+(根号2x-3)+(根号3x-5)+(根号4x-7)=5x-6
求导数 y=(x*根号x根号x根号x)/3次根号x^2
