What is the square root negative 16 over 9?

Answer 1

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.
