For z = 4-3i
Modulus of z

Explanation

To find the modulus of the complex number \( z = 4 - 3i \), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the real and imaginary parts**:
The complex number \( z \) can be expressed in the form \( z = a + bi \), where \( a \) is the real part and \( b \) is the imaginary part. For \( z = 4 - 3i \), we have:
- Real part \( a = 4 \)
- Imaginary part \( b = -3 \)
