whats the answer?
The answer to \( \sqrt{31} + \sqrt{31} \) is
\[ 2\sqrt{31} \]
This represents the result of adding the two square roots together. If you want a numerical approximation, \( \sqrt{31} \) is approximately \( 5.57 \), so:
\[ 2\sqrt{31} \approx 2 \times 5.57 \approx 11.14 \]
Therefore, \( 2\sqrt{31} \) is the exact answer, and approximately \( 11.14 \) as a numerical value.
