1. Start with the equation: √19 + √19.
2. Since both terms have the same radical (√19), we can simplify the expression by combining like terms.
3. Adding √19 + √19 gives us 2√19 as the result.
To add √19 + √19, you can simplify the expression by combining the terms. Since both terms have the same radicand (√19), you can add the coefficients outside the square root:
√19 + √19 = 1√19 + 1√19 = 2√19
So, the answer is 2√19.
