Question

Simplify the given expression.

square root negative 6 open parentheses 2 plus square root of negative 8

Answer 1

didn't understand question can you write in mathematical form?

Answer 2

sure

Answer 3

\[\sqrt{-6}\left( 2 + \sqrt{-8} \right)\]

Answer 4

dont you want answer in points?

Answer 5

6i(2+8i)
=12i+48i^2
=12i-48 if thats what you want

Answer 6

what do you mean? and no thats not one of my options

Answer 7

sqrt(-6) can also be written as 6i..where i=sqrt(-1)

Answer 8

12i-48i^2 isn't that your ans?

Answer 9

\[2\sqrt{6} + 4\sqrt{3}\]
\[-2\sqrt{6} + 4\sqrt{3}\]
\[-4\sqrt{3} + 2i \sqrt{6}\]
\[4\sqrt{3} + 2i \sqrt{6}\] these are my options

Answer 10

\[2\sqrt{-6} + \sqrt{-6}\sqrt{-8}\]\[2i \sqrt{6}+\sqrt{48}\]\[2i \sqrt6+4\sqrt{3}\]

Answer 11

@Sarkar you have them under square root yet...

\[\Large \sqrt{-6}(2+\sqrt{-8})=i\cdot \sqrt6(2+i\cdot \sqrt8)=\]

\[\Large 2i\sqrt6 +i^2\sqrt{8\cdot 6}=2i\sqrt6+(-1)\cdot \sqrt{48}\]

\[\Large 2i\sqrt6 -\sqrt{3\cdot 4^2}\]

\[\Large 2i\sqrt6 -4\sqrt{3}\]

Answer 12

but its not one of my options..

Answer 13

oh yes my mistake..option C then

Answer 14

ans is the third one

Answer 15

then I made a mistake somewhere O_O

Answer 17

Oh, I'm sorry, in my answer I accidentally lost a negative

Answer 18

no your ans is right

Answer 19

2iunder root6−4under root3 can also be wriiten as −4underroot3+2iunderroot6

Answer 20

didn't get?

Answer 21

what do you call that ? O_O

Answer 22

think its right@kreshnik

Answer 23
