Evaluate: `int(log)_(10)x\ dx`

Explanation

To evaluate the integral \( I = \int \log_{10} x \, dx \), we will follow these steps:

### Step 1: Change the Base of the Logarithm
We start by converting the logarithm from base 10 to base \( e \) (natural logarithm). We can use the change of base formula:

\[ \log_{10} x = \frac{\ln x}{\ln 10} \]
