To add the expressions 19−−√ and 19−−√, you can first simplify each square root separately and then add the simplified expressions together.

Let's simplify 19−−√ first.
To do this, find the square root of 19. The square root of 19 is a non-perfect square, so it cannot be simplified further without using decimal approximations. Therefore, the simplified form of 19−−√ is 2 Start Root 19 End Root.

Now let's simplify the second expression 19−−√, which is also 2 Start Root 19 End Root.

To add these simplified expressions together, simply add the numbers outside the square roots. In this case, both expressions have a number of 2 outside the square root.

So, adding 2 + 2 gives us 4. Therefore, the simplified form of 19−−√ + 19−−√ is 4 Start Root 19 End Root.
