Whenever you multiply two numbers, if they have the same sign, then the answer is positive.
When you multiply a number by itself, both numbers in the multiplication obviously have the same sign,
so the answer is positive.
So there's no number that gives a negative answer when you multiply it by itself.

you cant take the square root of a negative number
you cant get the square root of a negative number. nothing times itself would equal a negative number. if you have √-25 then its not possible. If you have -√25 then you take the square root of 25 and make it negative, so then it would be -5
The square root of a negative number is known as an imaginary number. In this case, the square root of negative 37 would be represented as √(-37) = √37i, where "i" is the imaginary unit equal to the square root of -1. This means that the square root of negative 37 is the square root of 37 multiplied by the imaginary unit "i".
Imaginary number
The square root of a negative number cannot be expressed with integers. The square root of a negative number is always imaginary.
