# How do you simplify ( 3i ) + ( 8 )?

A complex number is a number of the form $a + b i$ where $a$ and $b$ are real numbers. Once it is in this form, there is no further way to simplify it. There are other methods of representing a complex number, such as $R {e}^{i \theta}$ where $R$ and $\theta$ are real numbers, but it isn't a simplification.
