若(X-1)²与│2X+Y│互为相反数,求﹙﹣X﹚2010的次方＋Y³的值

若(X-1)²与│2X+Y│互为相反数,求﹙﹣X﹚2010的次方＋Y³的值
若(X-1)²与│2X+Y│互为相反数,求﹙﹣X﹚2010的次方＋Y³的值

若(X-1)²与│2X+Y│互为相反数,求﹙﹣X﹚2010的次方＋Y³的值
若(X-1)²与│2X+Y│互为相反数
(X-1)²+│2X+Y│=0
x-1=0,2x+y=0
x=1,y=-2
﹙﹣X﹚2010的次方＋Y³
=1-8
=-7

(X-1)²与│2X+Y│互为相反数，所以x=1 y=-2
﹙﹣X﹚2010的次方＋Y³的值:
1+(-8)=-7

(X-1)²+│2X+Y│=0 (X-1)²=0 x=1 │2X+Y│= │2+y │=0 y=-2 ﹙﹣X﹚2010的次方＋Y³=1-(-8)=9
