What is the real number part of the complex number?

The complex number given is \( 2 - 5i \). In a complex number of the form \( a + bi \), where \( a \) is the real part and \( b \) is the imaginary part, the real number part is \( a \).

For the complex number \( 2 - 5i \):

• The real part is \( 2 \).
• The imaginary part is \( -5i \).

Therefore, the real number part of the complex number \( 2 - 5i \) is \( 2 \).
