am i correct on this
radical (-121)
the radicand is negative 121
cannot be evaluated.
The square root of -121 is the imaginary number 11i, where "i" is the symbol for the square root of -1.
Actually, -11i is also an answer.
To evaluate the square root of a negative number, you will need to use complex numbers. In mathematics, the symbol "i" is used to represent the imaginary unit, which is defined as the square root of -1.
To find the square root of -121, you can rewrite it as √(-1) * √121. Taking the square root of -1 gives you the imaginary unit, so you have √(-1) * 11.
Since the square root of -1 can be represented as either "i" or "-i", you have two possible answers: 11i or -11i. Both of these are valid square roots of -121.
