The root sign X-2 and (y + 1) are opposite to each other, so we can find the Y power of X

The root sign X-2 and (y + 1) are opposite to each other, so we can find the Y power of X

solution
X-2 and (y + 1) &# 178 are opposite numbers
∴√x-2+(y+1)²=0
The absolute value and the square are nonnegative
∴x-2=0.,y+1=0
∴x=2,y=-1
∴x^y
=2^(-1)
=1/2
