Find the second order derivatives of the functions given.
`x^(20)`

Explanation

To find the second order derivative of the function \( f(x) = x^{20} \), we will follow these steps:

### Step 1: Find the first derivative
The first step is to differentiate the function \( f(x) = x^{20} \). We use the power rule for differentiation, which states that if \( f(x) = x^n \), then \( f'(x) = n \cdot x^{n-1} \).

Applying the power rule:
\[
f'(x) = 20 \cdot x^{20-1} = 20 \cdot x^{19}
