Complex Numbers!!! >_<
Simplify 7/10i

Answer 1

i dunno, that looks pretty simple already

Answer 2

usually this tends to mean multiply by the conjugate ....

Answer 3

I assume you mean \(\displaystyle\frac{7}{10i}\)

Answer 4

Yes

Answer 5

All you need - is multiply by i and divide by i, and remember, that i*i = -1, so...
7/(10i) = (7i)/(10i*i) = -(7i)/10 = -(7/10)*i
