√38 + √38

√38 + √38 = 2√38

explain

To simplify this expression, we can combine the two square roots. Both square roots are √38, so when we add them together, we get 2√38. This is the simplest form of the expression.

√29 - √29

√29 - √29 = 0.

Since both terms are the same, when we subtract them, they cancel each other out, resulting in zero.

√19 + √19

√19 + √19 = 2√19.

Similar to the previous explanation, both square roots are √19. When we add them together, we get 2√19. This is the simplest form of the expression.

3^√22 + 3√22 + √22

3^√22 + 3√22 + √22 cannot be simplified further, as the terms have different powers of the square root of 22 (√22).
