How do i get the answer : (200 * 10^3) - j1*10^3

I know theres 2 ways to solve it if i am not wrong.

The rectangular/polar form way.

Can anyone teach me step by step to get the answer? i am weak in complex number.

 

This might help

What step specifically are you having an issue with?

If you multiply both the numerator and the denominator by the complex conjugate of the denominator, then the denominator will beome a real number since j*(-j) = -(j^2) = 1
