![### Question
**30.** Evaluate the integral:
\[
\int (2 + x + 2x^2 + e^x) \, dx
\]
### Explanation
This problem requires finding the indefinite integral of the function \(2 + x + 2x^2 + e^x\) with respect to \(x\). The expression inside the integral combines polynomial terms with the exponential function \(e^x\). Each term can be integrated separately using basic integration rules:
- The integral of a constant \(a\) is \(ax + C\).
- The integral of \(x^n\) is \(\frac{x^{n+1}}{n+1} + C\), where \(n \neq -1\).
- The integral of \(e^x\) is \(e^x + C\).
Apply these rules to solve the integral, representing the result in a clear and simplified form.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fad35ec9e-c4ff-461f-8442-b935d287c97b%2F67b4232f-63b7-4ebf-9038-885e266427b0%2Ft591vfh_processed.png&w=3840&q=75)
![### Integral Problem
**Problem 35: Evaluate the integral**
\[
\int \left( \sqrt{x} + \frac{2}{\sqrt{x}} \right) \, dx
\]
---
This problem involves finding the indefinite integral of the sum of two functions: the square root of \(x\) and the reciprocal of the square root of \(x\) multiplied by 2.
**Steps for solving:**
1. **Decompose the integral** into two separate integrals:
\[
\int \sqrt{x} \, dx + \int \frac{2}{\sqrt{x}} \, dx
\]
2. **Integrate each part individually:**
- For the first integral, use the power rule for integrals:
\[
\int x^{1/2} \, dx = \frac{x^{3/2}}{3/2} = \frac{2}{3} x^{3/2} + C_1
\]
- For the second integral, rewrite the integrand in exponential form and apply the power rule:
\[
\int 2x^{-1/2} \, dx = 2 \cdot \frac{x^{1/2}}{1/2} = 4x^{1/2} + C_2
\]
3. **Combine the results:**
\[
\frac{2}{3} x^{3/2} + 4x^{1/2} + C
\]
Where \(C\) is the constant of integration representing an indefinite integral.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fad35ec9e-c4ff-461f-8442-b935d287c97b%2F67b4232f-63b7-4ebf-9038-885e266427b0%2F1q3wquq_processed.png&w=3840&q=75)
