What is the square root negative 16 over 9?
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.
