Answer 1

Answer:

$\pm \sqrt{-34} = \pm 5.831i$

Step-by-step explanation:

We have to express the given radical using imaginary unit.

$\sqrt{-34}$

We know that, imaginary unit:

$i = \sqrt{-1}$

We may solve the radical as:

$\pm \sqrt{-34}\\=\pm \sqrt{34\times -1}\\=\pm \sqrt{34}\times \sqrt{-1}\\=\pm \sqrt{34}\times i\\=\pm \sqrt{34}i\\\approx \pm 5.831i$
