You can't square root a negative number since no matter what you square, it will always be positive.
For example,
If you square -8 it would be 64 and not negative 64. Squaring a number means the number time the number. So -8 x -8 will become positive 64.
If you still don't understand feel free to ask again. Hope it helps.
