Answer 1

whats the answer?

Answer 2

To add \( \sqrt{31} + \sqrt{31} \), you can combine the two square roots.

\[
\sqrt{31} + \sqrt{31} = 2\sqrt{31}
\]

So, the final answer is:

\[
2\sqrt{31}
\]

Answer 3

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.
