Question

Z = 44i+ 23.3
What is the real part of z?
What is the imaginary part of z?

Answer 1

• real: 23.3
• imaginary: 44

Explanation:

The real part does not have i as a multiplier. It is 23.3.

The imaginary part* is the coefficient of i: 44.

_____

* There is some disagreement as to whether the imaginary part includes i or not. One source says the imaginary part is the part that has i as a factor (44i). Another source says the imaginary part is the real number that multiplies i (44). Above, we have used the latter definition. Please consult your curriculum materials for the definition you should use.
