If the square of a rational number is equal to itself, then the number is _____; if the cube of a rational number is equal to itself, then the number is _______. The square of a ______ is equal to his cube.

If the square of a rational number is equal to itself, then the number is _____; if the cube of a rational number is equal to itself, then the number is _______. The square of a ______ is equal to his cube.

(1) If the square of a rational number is equal to itself, then the number is _0,1____;
(2) If the cube of a rational number is equal to itself, then the number is __-1,0,1,____.
(3) The square of _0,1_____ is equal to his cube.

(1) If the square of a rational number is equal to itself, then the number is 0,1____;
(2) If the cube of a rational number is equal to itself, then the number is __-1,0,1,____.
(3) The square of _0,1_____ is equal to his cube.

Square equals its own rational number is ______, cube equals its own rational number is ______.

02=0,12=1,(-1)2=1, So the square is equal to its rational number 0,1;
And 03=0,13=1,(-1)3=-1, so the cube is equal to its rational number 0,±1.

02=0,12=1,(-1)2=1, So the square is equal to its rational number 0,1;
Again 03=0,13=1,(-1)3=-1, so the cube is equal to its rational number 0,±1.
