(xy分之x²-y²)²÷(x+y)²×(x-y分之x)³,其中x=3,y=2
(xy分之x²-y²)²÷(x+y)²×(x-y分之x)³,其中x=3,y=2
(xy分之x²-y²)²÷(x+y)²×(x-y分之x)³,其中x=3,y=2
(xy分之x²-y²)²÷(x+y)²×(x-y分之x)³,
=(x+y)²(x-y)²/x²y²÷(x+y)²× x³/(x-y)³
=x/y²(x-y)
=3/2²(3-2)
=3/4
(xy分之x²-y²)²÷(x+y)²×(x-y分之x)³,
=(x+y)²(x-y)²/x²y²÷(x+y)²× x³/(x-y)³
=x/y²(x-y)
=3/2²(3-2)
=3/4
