(-xy^2)^2·3x^2y÷(-xy^2)=(-xy^2)^2·3x^2y÷(-xy^2)=(-xy^2)^2·3x^2y÷(-xy^2)=原式=x²y^4*3x²y÷(-xy
(-xy^2)^2·3x^2y÷(-xy^2)=
(-xy^2)^2·3x^2y÷(-xy^2)=
(-xy^2)^2·3x^2y÷(-xy^2)=
原式=x²y^4*3x²y÷(-xy²)
=3x^4y^5÷(-xy²)
=-3x³y³
=x²y^4 × 3x²y ÷(-xy²)
=-3x³y³
(-xy^2)^2·3x^2y÷(-xy^2)=
=x²y^4×3x²y÷(-xy²)
=3x^4y^5÷(-xy²)
=-3x³y³
2x²y-3(2xy-xy)-xy
((xy+2)(xy-2)-2x²y²+5(xy-y)²)÷(2xy)
(x^2-xy)y÷y-x/xy怎么做?
xy-2{xy-[3x^2y-(4xy^2+0.5xy)]+4x^2y}+6xy^2
(X-3xy+4xy-y)-[-2x-2(xy-3/2xy)-y]+6xy的过程
[(2xy^3)^2÷(3x)]·[8xy÷(4xy)],其中x=1000,y=-1
3xy(x^2y-xy^2+xy)-xy^2(2x^2-6xy+2x)过程
计算:3xy(x²y-xy²+xy)-xy²(2x-xy+2x)
3xy^2-(XY^2-2X^2Y)÷(1/2xy)
计算(2xy的平方-3x的平方y+2xy)÷2xy结果
(3x²y-xy²+1/2xy)÷(-1/2xy)
(3x²y-xy²+1/2xy)÷(-1/2xy)
(3x^2y-xy^2+二分之一xy)÷(-二分之一xy)
(xy-x²)÷(x²-2xy+y²/xy)×(x-y/x²)
x-y/x²÷x²-2xy+y²/xy*(xy-x²)
计算(xy-y^2)÷x-y/xy
x^2-xy-6y^2+3xy+y+2
若xy=2(x+y),求 (3x-5xy+3y)÷(-x+3xy-y) 的值
