y-3/4y-8/(y+2-5/y-2)这如何化简
y-3/4y-8/(y+2-5/y-2)这如何化简
y-3/4y-8/(y+2-5/y-2)这如何化简
就这样吧.
y (3y^2+8y-3)-6y(3y+2y-1)+9y
6y-(y+2分之y+2-y分之y)÷(y^3-4y-2y^2+8分之y) 怎么算
2y+5/3y-6-y/2=5y-4/2y-4
2(y-4)(3y+2)-5(-3y+7)(y+1),其中y=-1
先化简,在求值:6y-(y+2分之y + 2-y分之y)除以y³-4y-2y²+8分之y,其中y= -2分之5先化简,在求值:6y-(y+2分之y + 2-y分之y)除以y³-4y-2y²+8分之y,其中y= -2分之5
y-3/4y-8/(y+2-5/y-2)这如何化简
计算y-3/4y-8÷(y+2-5/y-2)
y-3/4y-8÷(5/y-2-y-2) 计算`
4y(3y-2)-2y(6y+5)>8解不等式
(y-3)/(4y-8)÷(y+2-5/(y-2))
y-3/4y-8÷(5/y-2 -y-2) 一道数学题,
解方程:(y+4)/5+y+6=(y+8)/2-(y+4)/3要过程
3y-2(10-y)=4y-5(8-y)
(3y+2)(y-4)-3(y-2)(y-3)
(y^2)^4y-(-2y)^3y^6=
[T,Y]=ode45(@rigid,[0 1],[rand(15,1)]);plot(T,Y(:,1),'-',T,Y(:,2),'-.',T,Y(:,3),'.',T,Y(:,4),'-',T,Y(:,5),'-.',T,Y(:,6),'.',T,Y(:,7),'-',T,Y(:,8),'-.',T,Y(:,9),'.',T,Y(:,10),'-',T,Y(:,11),'-.',T,Y(:,12),'-.',T,Y(:,13),'.',T,Y(:,14),'-',T,Y(:,15),'.')
计算(x^8-x^7y+x^5y^3-x^4y^4+x^3y^5-x^y^7+y^8)(x^2+xy+y^2)
(4x-2y-z)-{5x[8y-2y-(x+y)]-x+(3y-10z)]=? kuaihuajian
