Answer:

$-\frac34 -\frac14 i$

Step-by-step explanation:

Let's start with distributing: $\frac1{4i}-\frac{3i}{4i}$ Simplify i with i in the second term, and rearrange. $-\frac34 +\frac1{4i}$ . Since i in the denominator looks ugly, let's multiply top and bottom by i. $-\frac34 +\frac i{4i^2} = -\frac34 +\frac i{4(-1)} =-\frac34 -\frac14 i$ . The middle passage is based on the fact that, by definition, $i^2=-1$

Integration of a power of x:

The integration of a power of x is:

$\int x^{n} dx = \frac{x^{n+1}}{n+1}$

In this question:

$n = 4$ . So

$\int x^{4} dx = \frac{x^{4+1}}{4+1} = \frac{x^5}{5}$

The result of the integration is $\frac{x^5}{5}$
