A complex number is typically expressed in the form a + bi, where a is the real part and b is the imaginary part. In this case, the complex number is 2 + 5i.
Breaking it down:
- The real part (a) is 2.
- The imaginary part (b) is 5.
Therefore, for the complex number 2 + 5i:
- Real part: 2
- Imaginary part: 5
This means that the value ‘2’ represents the position on the real number line, while ‘5i’ indicates the vertical displacement on the imaginary axis in the complex plane.
