Sum[\(40)Power[x,2],{i,1,20}]Divide[Sqrt[\(40)9Power[x,4]\(41)],Power[x,8]]Surd[i,4]+(5i+5)

It seems like you're mixing some operations involving summation, powers, roots, and complex numbers. Let's break down and interpret the expression.

I'll rewrite your input into clearer mathematical notation:

\[
\text{Sum}\left[ 40x^2 , \{i, 1, 20\}\right] \cdot \frac{\sqrt{9x^4}}{x^8} + \sqrt[4]{i} + (5i + 5)
\]

### Step-by-Step Breakdown:

1. **Summation**: The first part seems to indicate a summation over a constant value \(40x^2\) from \(i = 1\) to \(i = 20\). Since the summation is over a constant term:
   \[
   \sum_{i=1}^{20} 40x^2 = 20 \times 40x^2 = 800x^2
   \]

2. **Simplifying the Fraction**: 
   The second part is \(\frac{\sqrt{9x^4}}{x^8}\).
   \[
   \sqrt{9x^4} = 3x^2
   \]
   So the fraction simplifies to:
   \[
   \frac{3x^2}{x^8} = \frac{3}{x^6}
   \]

3. **Fourth Root of \(i\)**: 
   The next part is \(\sqrt[4]{i}\), which refers to the fourth root of the imaginary unit \(i\). The fourth roots of \(i\) are complex numbers, given by:
   \[
   \sqrt[4]{i} = e^{i\pi/8} \text{ or another equivalent form in polar coordinates.}
   \]

4. **Expression \(5i + 5\)**: 
   This is a simple complex number, \(5i + 5\), which can be written as \(5(1 + i)\).

### Putting It Together:
So, the entire expression becomes:
\[
800x^2 \cdot \frac{3}{x^6} + \sqrt[4]{i} + 5(1 + i)
\]
Simplifying the first part:
\[
\frac{800x^2 \cdot 3}{x^6} = \frac{2400}{x^4}
\]

Thus, the final expression is:
\[
\frac{2400}{x^4} + \sqrt[4]{i} + 5(1 + i)
\]

### Further Details:
1. The term \(\sqrt[4]{i}\) can be evaluated further for specific values if needed.
2. The expression is simplified in terms of \(x\) and involves both real and complex terms.

Do you want further details on the complex roots or more explanations? 

### Relative Questions:
1. What are the fourth roots of any complex number, including \(i\)?
2. How do you simplify expressions involving powers of variables?
3. Can the summation of a constant term be generalized for all constants?
4. How are roots of imaginary numbers computed in polar form?
5. What are the applications of summing polynomials?

### Tip:
When simplifying complex expressions, always break them down into individual terms, working with one operation at a time!
