Question

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

Answer 1

We can break this down by removing the parenthesis first:

-2 +
`√(-8)` + 5 -
`√(-50)`

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

-2 +
`2i√(2)` + 5 -
`5i√(2)`

Combine like terms:

-3 -
`3i√(2)` <-- that's the answer

Hope I helped :)
