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.
