Another one for my "impossible math problems" file.
The distance between real parts of these numbers is 3-(-3) = 6. The distance between imaginary parts of these numbers is (4-(-3)) = 7. The straight-line distance on the complex plane between these numbers is given by the Pythagorean theorem as distance = √(6² + 7²) distance = √85 ≈ 9.2195
_____ If your answer choices are supposed to have radical signs, then the best choice is ... D) √85
