Question

anonymous · Answer

that depends, are imaginary numbers acceptable?

anonymous · Answer

Has to be positive.

anonymous · Answer

no i think only real numbers are accepted

anonymous · Answer

Or non-negative at any rate.

anonymous · Answer

okay than the restrictions, the number must be positive under the radical and the domain is $$x \ge2$$

anonymous · Answer

I reckon...

anonymous · Answer

That's a 3 right? Not a cube root?

anonymous · Answer

Someone fooled me with that yesterday...

anonymous · Answer

wait is it a 2 0r a 3

anonymous · Answer

Nerdanonymous is right...

I was just checking that the 3 in front of the square root is just the number 3 (and not a 3 meaning cube root instead of square root).

anonymous · Answer
