$$\int\limits_{0}^{1} 2^{2 x + 1}\, dx$$

Integral(2^(2*x + 1), (x, 0, 1))

Detail solution

There are multiple ways to do this integral.
Method #1
1. Let $u = 2 x + 1$ .
  
  Then let $du = 2 dx$ and substitute $\frac{du}{2}$ :
  
  $\int \frac{2^{u}}{2}\, du$
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\int 2^{u}\, du = \frac{\int 2^{u}\, du}{2}$
    1. The integral of an exponential function is itself divided by the natural logarithm of the base.
      
      $\int 2^{u}\, du = \frac{2^{u}}{\log{\left(2 \right)}}$
    So, the result is: $\frac{2^{u}}{2 \log{\left(2 \right)}}$
  Now substitute $u$ back in:
  
  $\frac{2^{2 x + 1}}{2 \log{\left(2 \right)}}$
Method #2
1. Rewrite the integrand:
  
  $2^{2 x + 1} = 2 \cdot 2^{2 x}$
2. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int 2 \cdot 2^{2 x}\, dx = 2 \int 2^{2 x}\, dx$
  1. Let $u = 2 x$ .
    
    Then let $du = 2 dx$ and substitute $\frac{du}{2}$ :
    
    $\int \frac{2^{u}}{2}\, du$
    1. The integral of a constant times a function is the constant times the integral of the function:
      
      $\int 2^{u}\, du = \frac{\int 2^{u}\, du}{2}$
      
      The integral of an exponential function is itself divided by the natural logarithm of the base.
      
      $\int 2^{u}\, du = \frac{2^{u}}{\log{\left(2 \right)}}$
      
      So, the result is: $\frac{2^{u}}{2 \log{\left(2 \right)}}$
    Now substitute $u$ back in:
    
    $\frac{2^{2 x}}{2 \log{\left(2 \right)}}$
  So, the result is: $\frac{2^{2 x}}{\log{\left(2 \right)}}$
Method #3
1. Rewrite the integrand:
  
  $2^{2 x + 1} = 2 \cdot 2^{2 x}$
2. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int 2 \cdot 2^{2 x}\, dx = 2 \int 2^{2 x}\, dx$
  1. Let $u = 2 x$ .
    
    Then let $du = 2 dx$ and substitute $\frac{du}{2}$ :
    
    $\int \frac{2^{u}}{2}\, du$
    1. The integral of a constant times a function is the constant times the integral of the function:
      
      $\int 2^{u}\, du = \frac{\int 2^{u}\, du}{2}$
      
      The integral of an exponential function is itself divided by the natural logarithm of the base.
      
      $\int 2^{u}\, du = \frac{2^{u}}{\log{\left(2 \right)}}$
      
      So, the result is: $\frac{2^{u}}{2 \log{\left(2 \right)}}$
    Now substitute $u$ back in:
    
    $\frac{2^{2 x}}{2 \log{\left(2 \right)}}$
  So, the result is: $\frac{2^{2 x}}{\log{\left(2 \right)}}$
Now simplify:

$\frac{4^{x}}{\log{\left(2 \right)}}$
Add the constant of integration:

$\frac{4^{x}}{\log{\left(2 \right)}}+ \mathrm{constant}$

The answer is:

$\frac{4^{x}}{\log{\left(2 \right)}}+ \mathrm{constant}$
