Question

27. (-2 + √-8) + (5 - √-50) standard form ?​

Answer 1

We can break this down by removing the parenthesis first:

-2 + $\sqrt{-8}$ + 5 - $\sqrt{-50}$

In order to continue, you have to simplify the square roots by factoring it and taking out i:

-2 + $2i\sqrt{2}$ + 5 - $5i\sqrt{2}$

Combine like terms:

-3 - $3i\sqrt{2}$ <-- that's the answer

Hope I helped :)
