Rounded to the nearest whole number it would be 13
<span>To be both complex and imaginary, the answer would have to include "i" as well as have the form "a + bi". The first example, 3i - 5, fits. This would look to be the only example that does fit. The negative square root of 14 would be imaginary, but not complex.</span>
Answer: 11.775

1/8, 7/2, 5/6, 10/3
