xyxy
xy^5-xy^4+xy-x因式分解分组分解法原式=x(y^5-y^4)+x(y-1)=xy^4(y-1)+x(y-1)=x(y^4+1)(y-1)
xy^5-xy等于多少原式=xy(y^4-1)=xy(x²+1)(x²-1)=xy(x²+1)(x+1)(x-1)
2xy(5xy的2次方+3xy-1)2xy(5xy²+3xy-1)=10x²y³+6x²y²-2xy很高兴为您解答,【学习宝典】团队为您答题.请点击下面的【选为满意回答】按钮,谢
2xy(5xy的2次方+3xy-1)2xy(5xy的2次方+3xy-1)=10x^2y^3+6x^2y^2-2xy
计算(xy)^5/(xy)^3/(-xy)要过程!（xy)^5/(xy)^3/(-xy)=-xy^(5-3-1)=-xy如追加其它问题,采纳本题后点击想我求助,原式=(xy)^5-3/(-xy)=(xy)^2/(-xy)=(-1)(xy)^
xx+xy=xy,xy染色体吧
xy×(xy)²-3xyx^2+y^2-3xy=4x^2+y^2+2xy-5xy=4(x+y)^2-5xy=43^2-5xy=45xy=9-45xy=5xy=1这要是问什么啊
化简：根号（xy^5)y的平方根号xy.(按顺序写,由于不好打平方根号）根号（xy^5)=y²√﹙xy﹚
5xy²-{2x²y-[3xy²-（4xy²-2xy²）]}其中x=2,y=-15xy²-{2x²y-[3xy²-（4xy²-2xy²）]}
5xy²-{2x²y-[3xy²-(4xy²-2xy²)]}=5xy²-{2x²y-[3xy²-(4xy²-2xy²)]}=5xy²
((xy+2)(xy-2)-2x²y²+5(xy-y)²)÷(2xy)((xy+2)(xy-2)-2x²y²+5(xy-y)²)÷(2xy)解,得：==(x^2y^2-4-2x&#
(-3xy+2xy)-(4xy+xy)(-3xy+2xy)-(4xy+xy)=-xy-5xy=-6xy-6xy去括号后合并同类项原式=-3xy+2xy-4xy-xy=(-3+2-4-1)xy=-6xy先括号内化简，再去括号相减(-3xy+2
⒈2(Xy+Xy)-3(Xy-xy)-4Xy,其中X=1,y=-1⒉1/2ab-5⒈2(Xy+Xy)-3(Xy-xy)-4Xy,其中X=1,y=-1⒉1/2ab-5aC-(3acb)+(3aC-4aC),其中a=-1,b=2,C=-2
X-Y=5,XY=3.XY是多少?Y=X-5XY=X²-5X=3X²-5X-3=0X=(5±√37)/2Y=X-5X=(5-√37)/2,Y=(-5-√37)/2X=(5+√37)/2,Y=(-5+√37)/2x=(5±
X+y=3xy=-5Xy=?X+y=3xy=-5X-y=?(x-y)^2=(X+y)^2-4xy=9+20=29则x-y=±根号29
分式化简xy-5y/10y+2xy
求导dy/dx及微分xy=e^xy+5两端对x求导得y+xy'=e^(xy)*(y+xy')整理即可得dy/dx=y两边同时微分：d（xy）=d（e^xy）即：ydx+xdy=ye^xydx+xe^xydyy(1-e^xy)dx=x(e^x
5x^2y/-1/2xy*3xy^25x^2y/-1/2xy*3xy^2=-7.5x²y²
2xy+5y^2+()=x^2+3xyx^2+xy-5y^22xy+5y^2+()=x^2+3xy()=x^2+3xy-2xy-5y^2()=x^2+xy-5y^2()中填x^2+xy-5y^2
