To add √31 + √31, we can rewrite both square roots as a single term:
√31 + √31 = 2√31
So, √31 + √31 equals 2√31.
To add √31 + √31, we can simplify it by recognizing that both terms have the same square root. The square root of 31 cannot be simplified further since it is not a perfect square. Therefore, we can simply add the coefficients of the square roots and keep the square root symbol intact. The sum of the coefficients would be 1 + 1 = 2. So, √31 + √31 equals 2√31.
