Simplify the expression. -5+i/2i

  1. Steve

    Just multiply top and bottom by i.

    What do you get, since i^2 = -1 ?

  2. Xspead

    1/2+5/2i right?

  3. Steve

    correct

    although the way you wrote it could easily be seen as 1/2 + 5/(2i), especially since that is the way you meant it in your original expression.

    Since you know what you meant, and you're probably submitting it in writing, it will probably come out ok, but online you need to make it clear. Try

    1/2 + 5/2 i
    or
    1/2 + (5/2)i
