You can use trigonometric functions to simplify (6 e^{(3 \pi)/8 i}) into a non-exponential complex number by expressing it in trigonometric form.

The expression (e^{(3 \pi)/8 i}) can be written in trigonometric form as (e^{i\theta} = \cos(\theta) + i \sin(\theta)), where (\theta = (3\pi)/8).

Therefore, (6 e^{(3 \pi)/8 i}) can be written as (6(\cos((3\pi)/8) + i\sin((3\pi)/8))).

Now, you can simplify using trigonometric identities to find the cosine and sine of ((3\pi)/8).

Finally, the expression can be written as a non-exponential complex number in the form (a + bi), where (a) is the real part and (b) is the imaginary part.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
