Solved Example on Real Part
Ques: Choose the real part of the complex number 36 + 2i.
Choices:
A. real part = 36i
B. real part = 36
C. real part = 2i
D. real part = 38
Correct Answer: B
Solution:
Step 1: The real part of the complex number Z = a + ib is a and imaginary part is the coefficient of i i.e., b
Step 2: The real part of the complex number 36 + 2i is 36. [The real part of the complex number a + ib is a.]
