计算:根号下X(X+Y)除根号下X+Y分之XY方
计算:根号下X(X+Y)除根号下X+Y分之XY方
计算:根号下X(X+Y)除根号下X+Y分之XY方
是否这样:
√[x+y)/xy²]÷√x(x+y)
=√[(x+y)/(x+y)x²y²]
=√1/x²y²
=1/|x||y|
计算:根号下X(X+Y)除根号下X+Y分之XY方
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)=
计算(x根号下y-y的根号下x)/根号下xy
(x*根号下x + x*根号下y ) / (xy-y^2) — (x + 根号下xy + y) /(x*根号下x — y*根号下y)
arctan根号下(y/x)=x/y,计算微分
(x+y)/(根号下x+根号下y)+2xy/(x根号下y+y根号下x)=______.(x+y)/(根号下x+根号下y)+2xy/(x根号下y+y根号下x)=______.
若x>0,y>0,且根号下x(根号下x+根号下y)=3根号下y(根号下x+5根号下y),求(2x+2根号下若x>0,y>0,且根号下x(根号下x+根号下y)=3根号下y(根号下x+5根号下y),求(2x+2根号下xy+3y)/(x-根号下xy+y
计算:(根号下x+xy-根号下xy)(根号下y+y²+y)(x>0,y>0);
计算:(根号下x+xy-根号下xy)(根号下y+y²+y)(x>0,y>0)
计算 (根号下x+xy-根号下xy)(根号下y+y的平方+y)(x>0 y>0) 快啊.
y=根号下(x+根号x) 求导如题 y=根号下(x+根号x)求导
化简:[(x×根号x+x×根号y)/(xy-y²)]-[(x+根号下xy+y)/(x×根号x-y×根号y)]
X-Y除以根号下X减根号Y
化简 x乘以根号下(y/x
X根号下负X平方Y
已知x,y为实数,且y=根号下(9-x)+根号下(x-9)+9,求根号下(x)根号下(y)的值
根号(y分之x)+(x分之y)+2-根号下x分之y-根号下y分之x+根号下xy求!
