I've attached an equation with the answer, but If someone can show how this equation was solved.

50/ [50(4+3j) + 100]100= 20+ 10i

Do you know enough of the algebra of complex numbers to understand the solution. If not this might be a good time for a review.

ETA: I don't think you have rendered the expression correctly. The screenshot and your expression have the left square brace in different locations. Which is it? I also think that you transcribed the number incorrectly.

BTW, is that mixing old and new methods of complex numbers. Old = a+ib new=a+jb or is this (as I suspect) just current fashion.

BTW, I was serious when I said "ask chatGPT" I'd be interested in the answer.

we take inductor as it is but for capacitor we take 1/c check whether you have made mistake in that..

Appears to be another case of someone who want their homework solved by someone else.
