同类题1

下列四个命题：（1）已知向量

\overset{⇀}{a}, \overset{⇀}{b}, \overset{⇀}{c}

是空间的一组基底，则向量

\overset{⇀}{a} + \overset{⇀}{b}, \overset{⇀}{a} - \overset{⇀}{b}, \overset{⇀}{c}

也是空间的一组基底；（2）在正方体

A B C D - A_{1} B_{1} C_{1} D_{1}

G

Δ A_{1} B D

\overset{⇀}{A G} = x \overset{⇀}{A D} + y \overset{⇀}{A B} + z \overset{⇀}{C C_{1}}

x + y + z

的值为1；（3）圆

{(x - 3)}^{2} + {(y - 3)}^{2} = 9

3 x + 4 y - 11 = 0

的距离等于1的点有2个；（4）方程

(x^{2} + y^{2} - 2) \sqrt{x - 3} = 0

表示的曲线是一条直线.其中正确命题的序号是____.
