## anonymous 5 years ago How do you get rid of the "i" in 1i, what about 13i?

1. anonymous

Who put the i in it? i^2=-1

2. anonymous

$1i=\sqrt{-1}$ $13i=13\sqrt{-1}$

3. anonymous

you can use that radical sign..

4. anonymous

multply it by itself...? like 1i x 1i = i^2 = -1 like what chaguanas said...

5. anonymous
