I think you mean -1, not underscore 1. Usually the i-axis is the direction of the y-axis on x-y plots, so it would bt 5 to the right and 2 up, or (5,2) in x-y systems. --------------- 3. what is the value of i the power of 4? ---------------- 4.If a and b are non-zero numbers,what is 1/(a+bi) Multiply NUM and DEN by the conjugate of the DEN a-bi 1/(a+bi) = (a-bi)/(a^2 + b^2)
