The real part of 3 is 3 and the imaginary part of 3 is 0.

Work Step by Step

Complex numbers are written in the form a+bi, with a being the real number and b being the imaginary number. Since there is no "i" in this complex number, b must be 0 since i*0 = 0. Therefore a=3, so a is the real part of the number and 0 is the imaginary part.
