no, it is actually not a real number.

It falls under the category of a imaginary number which is the square root of -1 or as the variable i

Because the square root of -4 is 2i because the square root of 4 is 2 and if you take i out it will maek it a positive

so it goes like this

-4 SR= 2i

-9 square root= 3i

and so on
