can this be written using "i" ?
(-1 + √(-11)) / (2)
i know that √-1 becomes + or - i
sure
√-11 = i√11
so (-1 ± √-11)/2
= (-1 ± i√11)/2
thank you
Yes, the expression (-1 + √(-11)) / 2 can be written using the imaginary unit "i".
To do this, let's simplify the expression first.
Starting with the expression √(-11), since √(-1) is equal to "i", we can rewrite √(-11) as √(11) * √(-1).
So, (-1 + √(-11)) / 2 becomes (-1 + √(11) * √(-1)) / 2.
Now, we can substitute √(-1) with "i".
(-1 + √(11) * √(-1)) / 2 becomes (-1 + √(11) * i) / 2.
Therefore, the expression (-1 + √(-11)) / 2 can be written using "i" as (-1 + √(11) * i) / 2.
