Add √19 + √19 .(1 point)
√19 + √19 simplifies to 2√19.
To add √19 + √19, we can simplify it by adding the coefficients (numbers in front of the square root) and keeping the square root part the same. Since the coefficients are both 1, the answer would be 1 + 1 = 2. Therefore, √19 + √19 = 2.
To add √19 and √19, we can treat them as like terms because they have the same radical, which is √19.
Step 1: Combine the coefficients in front of the radicals. In this case, the coefficients are both 1.
1 + 1 = 2
Step 2: Write the result together with the common radical.
2√19
So, √19 + √19 = 2√19.
