Are you allowed imaginary numbers?

Also, what do you think is the correct answer?

4. anonymous

Well, what do you think is the correct answer?

5. anonymous

@Nixy I believe it is the first one.

6. anonymous

It is the second one.

The reason why it is the second one is because if you put -5 in $$\huge \sqrt{x-2}$$ $$\huge \sqrt{-5-2}$$ we get $$\huge \sqrt{-5-2} = i\sqrt{7}$$ which is an imaginary number and not a real number

@Nixy thank you.
