No it is an Imaginary Number√-16 = 4ii is the square root of negative one
-4
The negative square root of 16 can be either +4 or -4 . Both are correct.
sqrt(16/9) = sqrt(16) / sqrt(9) = 4/3 .That's the square root of positive 16/9. There is no square root of a negative number, unlessyou want to get into what's called "imaginary" numbers in math and engineering.If you want the square root of -(16/9), or (-16)/9, or 16/(-9), in each case it's (4/3)i .That little ' i ' is the unit imaginary number, defined as the square root of (-1).That's probably as far into it as we ought to go for right now.

The negative square root of 16 is -4. It can be written as the ratio of 792 to -198, so it's rational.

-16 i think
The square root of the fraction 16 over 169 is 4 over 13.
sqrt(16/9) = sqrt(16) / sqrt(9) = 4/3 .That's the square root of positive 16/9. There is no square root of a negative number, unlessyou want to get into what's called "imaginary" numbers in math and engineering.If you want the square root of -(16/9), or (-16)/9, or 16/(-9), in each case it's (4/3)i .That little ' i ' is the unit imaginary number, defined as the square root of (-1).That's probably as far into it as we ought to go for right now.
4 over square root of 16 simplifies to 1 !
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.
