1 answer

To simplify the expression, we need to combine like terms.

First, let's simplify the square root expressions individually.

√31 is an irrational number and cannot be simplified further.

Next, let's combine the two square root expressions.

√31 + √31 = 2√31

Therefore, the simplified expression is 2√31.
