that will be an imaginary number because it's not possible to have negative square roots.

No I haven't. I have to find the principal square root & the negative square root. Also I must determine if it is rational and/or a perfect square.

If so, then \( \sqrt{-23} = \sqrt{-1 \times 23} = \sqrt{-1}\sqrt{23} = i\sqrt{23} \)

If you haven't learned imaginary numbers, then the answer is that -23 has no square root.
