19i

A number in the form \(\displaystyle{a}+{b}{i}\) is called a complex number, where:

The value a is called the real part of the complex number

The value b is called the imaginary part

Therefore,

\(\displaystyle{19}=\underbrace{{{0}}}_{{a}}+\underbrace{{{19}}}_{{b}}{i}\Rightarrow{a}={0}\) and b=19

Real part = 0; Imaginary part = 19
