Answer 4

\[\frac{ -5+\iota }{ 2 \iota }\times \frac{ \iota }{ \iota }=\frac{ -5 \iota +\iota^2 }{ 2 \iota^2 }=?\]

Answer 5

\[\iota^2=-1\]

Answer 6

here only iota in the denominator so try to make it i^2
if you have more terms always multiply the conjugate of the denominator
for example if you have a+b iota in the denominator
then multiply by (a-b iota )/(a-b iota)
