If the even power of a rational number is not a negative number, then the rational number is Please, heroes.
Any rational number
The even power of a rational number (outside 0)(not required to be positive) is a positive number
0 Has no negative power and zero power, and positive power is 0
Any rational number
The even power (not positive) of a rational number (outside 0) is a positive number
0 Has no negative power and zero power, and positive power is 0
