Transform Rectangular notation into still rectangle but with exponential

Hi!

My teacher wrote the following equivalence:
1.JPG

If you can not see the image, the equivalence is as follows:

(1.10^-3 ) . 10 . [ (j.500)/ (j+1)] x [e^(0.j)] = 3,5 . e^0,70.j

I think he transformed from the form:
a+b.j
into
|z|.e^(j.theta) which is equal to [Square root(a^2 +b^2)] . e^[j . arctg(b/a)]

I Reduced the first expression (1.10^-3 ) . 10 . [ (j.500)/ (j+1)] x [e^(0.j)] into 5+ 5.j
But obviously what gave me does not lead to the desired result:
3,5 . e^0,70.j

I don't understand what I can possibly did wrong or if there is another way to get this equivalence.

Thank you!

I don't see a "7" in the original line. In any case, I can't make sense of what is done. Was there any context that might help by suggesting how the original equation was obtained?
