No it is an Imaginary Number√-16 = 4ii is the square root of negative one
The negative square root of 16 can be either +4 or -4 . Both are correct.
Positive or negative 4i
4i square root of 16 is 4, but negative square roots aren't real so the i means its imaginary.

The negative square root of 16 is -4. It can be written as the ratio of 792 to -198, so it's rational.
The negative square root of 16 can be either +4 or -4 . Both are correct.
-16 i think
it is impossible to get the square root of a negative, since the definition of a square root is something times itself. example: the square root of 16 is 4 because 4 x 4 = 16. and a negative times a negative is a positive, so the square root of a negative is impossible. however, you can do the square root of 121 (which is 11) and make the 11 a negative. 11 x 11 = 121 and -11 x -11 = 121 but you could make 11 negative after the fact, if that is what you wanted to do.
Positive or negative 4i
There is no square root of negative 8, negative numbers can never be square rooted since no two of the same number can go into a negative number, for example 16's square root is 4 and -4 since 4x4=16 and -4x-4=16, but -16 doesn't have a square root since -4 just turns into a positive when multiplied to itself.
The square root of a real number is not always positive. The square root of any positive number is positive, the square root of zero is zero (not positive), and the square root of a negative number is complex (i.e. neither positive nor negative). The square root of 16 = -4 or 4. The square root of 0 = 0 The square root of -16 = -4i or 4i
√4 × 16 = ±2 × 16 = ±32 (though the √ symbol normally means the positive square root). √(4 × 16) = √64 = ±8
4i square root of 16 is 4, but negative square roots aren't real so the i means its imaginary.
A positive number has two square roots, its principal (positive) root and its negative root. This is because a negative number multiplied by a negative number equals a positive number. In this instance, the square roots of 256 are 16 and -16.
