1. anonymous

$\sqrt{-9}$

2. anonymous

$i = \sqrt{-1}$

3. anonymous

so its 9?

4. anonymous

$= 3i$

5. anonymous

$\sqrt{-9} = \sqrt{-1} * \sqrt{9}$ $\sqrt{9} = 3$

6. anonymous

so its 3?

7. anonymous

$-\sqrt{9}=(-1)*\sqrt{9}=(-1)*3=-3 and \it is also equal \to (-1)*(-3)=3$

8. anonymous

most of the time people just want the postive number if you take the squareroot - so if only one answer is correct I would take -3

9. anonymous

$-\sqrt{9}\ or\ \sqrt{-9}?$

10. anonymous

@yoyogators which is it?

11. anonymous

Okay so the answer is 3

12. anonymous

$-\sqrt{9}$

13. anonymous

Depending which of the two square roots you are referring to... if its$\sqrt{-9}$then yes.

14. anonymous

If it's $-\sqrt{9}$ then it's like saying $-1 \times \sqrt{9}$

15. anonymous

$\sqrt{9} = 3$3 * -1 = negative 3
