已知|2x-6|与(y+1)^2互为相反数,求(1) y^x的值;(2) x^3-y^2014的值

已知|2x-6|与(y+1)^2互为相反数,求(1) y^x的值;(2) x^3-y^2014的值
已知|2x-6|与(y+1)^2互为相反数,求(1) y^x的值;(2) x^3-y^2014的值

已知|2x-6|与(y+1)^2互为相反数,求(1) y^x的值;(2) x^3-y^2014的值
|2x-6|>=0,(y+1)^2>=0,0与0互为相反数,所以2x-6=0,y+1=0
x=3,y=-1
(1)y^x=-1,(2)x^3-y^2014=3^3-(-1)^2014=27-1=26
