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, unless
you 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.

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.

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.
The positive square root of 256 is 16 because 16 multiplied by 16 equals 256. The negative square root of 256 is -16 because -16 multiplied by -16 also equals 256. In general, for any positive number x, the square roots of x are both a positive and a negative number, with the positive square root being the principal square root.
-16 i think
The square root of the fraction 16 over 169 is 4 over 13.
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.
