Question 357955: Hi, I have no idea even were to begin with this problem. I have to show my work, but do not understand how to obtain the answer. If you can show me the steps I would perform, I would greatly appreciate it.
Complex numbers are used in electronics to describe the current in an electric circuit. Ohm's law relates the current in a circuit, I, in amperes, the voltage of the circuit, E, in the volts, and the resistance of the circuit, R, in ohms, by the formula E=IR. Use this formula to solve.
SEction 10.7
115.)
Find E, the voltage of a circuit, if I = (4-5i) amperes and R= (3+7i) ohms.

------
Formula: E = IR
E = (4-5i)(3+7i)
E = 12+35 +28i-15i
E = 47 +13i
