已知xy满足/ x-2/+(y+1)²=0试求代数式试求代数式-2xy乘5xy²+1/2x²y²乘2y-3x乘2y+6xy的值
已知xy满足/ x-2/+(y+1)²=0试求代数式
试求代数式-2xy乘5xy²+1/2x²y²乘2y-3x乘2y+6xy的值

已知xy满足/ x-2/+(y+1)²=0试求代数式试求代数式-2xy乘5xy²+1/2x²y²乘2y-3x乘2y+6xy的值
/ x-2/+(y+1)²=0
x-2=0
x=2
y+1=0
y=-1
-2xy乘5xy²+1/2x²y²乘2y-3x乘2y+6xy
=-10x²y³+x²y³-6xy+6xy
=-9x²y³
=-9x2²x(-1)³
=36
