Question

.

Answer 1

That would be \[\sqrt{6}i\] and \[3\sqrt{2}i\] making it \[(\sqrt{6}+3\sqrt{2})i\]

Answer 2

\[\sqrt{6}i+3\sqrt{2}i\]

Answer 3

no, because if you have an 'i' than there shouldn't be a negative on the outside

Answer 4

what are your options?

Answer 5

those answers are only if you multiply , not add
is your problem \[\sqrt{-6}\times \sqrt{-18}\]?

Answer 6

it's okay, if it were that, then the answer would be -6√3

Answer 7

glad to be of assistance :)
