The problem is to evaluate the limit:

\[
\lim_{x \to 10} \sqrt{3x + 1}
\]

### Step-by-step solution:

1. **Direct Substitution**:
   Since there are no indeterminate forms (like \( \frac{0}{0} \) or \( \infty - \infty \)), we can directly substitute \( x = 10 \) into the expression \( \sqrt{3x + 1} \).

   \[
   \lim_{x \to 10} \sqrt{3x + 1} = \sqrt{3(10) + 1}
   \]

2. **Simplify the expression**:
   \[
   \sqrt{3(10) + 1} = \sqrt{30 + 1} = \sqrt{31}
   \]

So, the value of the limit is:

\[
\boxed{\sqrt{31}}
\]
