To add √19 + √19, you can simplify it by combining like terms. In this case, both terms have the same radicand, which is 19.
When you add two terms with the same radicand, you add the coefficients together and keep the radicand the same.
So, √19 + √19 equals 2√19.
Therefore, the correct answer is 4. 2√19.

To add √19 + √19, you can follow these steps:
Step 1: Simplify the square roots separately.
√19 can't be simplified further because 19 is not a perfect square. So, it remains as √19.
Step 2: Combine the like terms.
Since we have two √19 terms, we can combine them.
√19 + √19 = 2√19
Therefore, the sum of √19 + √19 is 2√19.
So, the correct option is 4. 2√19.
