Questions & Step-by-Step Solutions
Find the real part of the complex number z = 5 - 2i.
Correct Answer: 5
Step 1: Identify the complex number given in the question, which is z = 5 - 2i.
Step 2: Understand that a complex number is made up of a real part and an imaginary part.
Step 3: In the complex number z = 5 - 2i, the real part is the number before the 'i'.
Step 4: Look at the number before 'i' in z = 5 - 2i, which is 5.
Step 5: Conclude that the real part of the complex number z is 5.
