To check the real part of a complex number, we need to recall the general form of a complex number, which is:

\[
z = a + bi
\]

Where:
- \(a\) is the **real part** of \(z\),
- \(b\) is the coefficient of the imaginary part (associated with \(i\), the imaginary unit).

For example, if \(z = 4 + 3i\), the real part is \(a = 4\).

If you have a specific complex number you'd like me to work with, feel free to provide it, and I can help you find the real part of that number!

Would you like more details on complex numbers or have any questions about this? Here are some related queries you might find helpful:

1. How do you extract the real part of a complex number in polar form?
2. What is the difference between real and imaginary parts in complex numbers?
3. How can you graphically represent the real part of a complex number on the complex plane?
4. What is the real part of a sum or product of complex numbers?
5. How does the real part of a complex number relate to its conjugate?

**Tip**: The real part of a complex number remains unchanged under conjugation. So, if \( z = a + bi \), the conjugate \( \overline{z} = a - bi \) has the same real part \(a\).

Understand how to check the real part of a complex number using the formula z = a + bi, where a is the real part. Explore examples and key concepts related to complex numbers and their conjugates. Ideal for students in Grades 9-12.
