Why exactally does the absolute value of 3+4i = 5. I know (3) squared plus (4i) squared = 5? Could you include a graphic approach as well? Thank you.

i is an imaginary number. YOu can graph it only on the complex number plane.
Consider a rectangular graph, the x axis is the real numbers, and the y axis is imaginary numbers. THen you plot the point (3,4). Find the distance from the origin, it is 5.
