Question

any one know anything about the terms i? i have a problem i cant figure out.
-(sqrt)-496(both are negatives)

Answer 1

So you have: \[-\sqrt{-496}\]
Well, i is defined as \[\sqrt{-1}\].
So you can rewrite this as:
\[-\sqrt{(-1)(496)}\].
Then:
\[-(\sqrt{-1}\sqrt{496})\].
So this becomes.
\[-\sqrt{496}i\]
