simplify the expression
5+i/2i

I suspect you may mean
(5 +i)/(2i)
be careful about what is numerator and what is denominator when typing.
If my guess is correct then multiply top and bottom by i
(5 i + i*i) / (2i*i)
But
i * i = i^2 = 1
so
(5 i  1) /2
which is
1/2 + (5/2)i 
Thanks but I had figure it out
thanks again
