We are not here to give you answers. You are not allowed to post questions without showing your own attempts first. And, as Les said, if this is homework and you don't know how to do it, then ask your teacher and start paying attention in class. You are not entitled to anything here, the members of ETO VOLUNTEER their time. Don't expect to get something without giving something yourself. It is you who is arrogant. If you don't like it here, then leave. It's as simple as that.I think all ppl here look so arrogant and talk so much. Don't seem like helpful ppl. Maybe study too much till crazy
Change the side change the sign!!! That's how most do it!!Les Jones. You simply take 0.131 and slide it diagonally to the other side of the equation and then take 1.683 to the other side and change the sign to positive. Then read the equation backwards.
No complex multiplication required.
