Am I doing this right ? complex numbers

[jhon13]

Hello everyone!

I'm a bit unsure if I understanding this right, could someone see if I'm getting the right answers?

1) W = 1 + 7i and Z = - 2 + 3i

find I Z I (modulus of Z) = square root 13

find (conjugate of Z) = - 2 - 3i

find (reciprocal of Z) = -2 -3i / 13

find W * Z = ( - 2 - 21 ) + ( 3 - 14 )i

find W / Z = ( - 16 - 24i) / 13

jhon13,

you asked in your headline "Am I doing this right?"

We can't knowthat if you won't type out your steps here.

you're "doing it right."
