19i

A number in the form$a+bi$ 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,

$19=\underset{a}{\underset{\u23df}{0}}+\underset{b}{\underset{\u23df}{19}}i\Rightarrow a=0$ and b=19

Real part = 0; Imaginary part = 19

A number in the form

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

The value b is called the imaginary part

Therefore,

Real part = 0; Imaginary part = 19
