Let's combine the expressions step-by-step.

1. For the first expression:
  2√k + √k - 3√k = (2 + 1 - 3)√k = 0√k = 0

2. The second expression remains as:
  √(3k)

3. The third expression:
  0 - √k = -√k

4. The fourth expression is simply:
  0

Now, adding all these together:
  0 + √(3k) + (-√k) + 0 = √(3k) - √k

Thus, the combined expression is:
  √(3k) - √k
The combined expression is $$ \sqrt{3k} - \sqrt{k} $$.

Combine the following expressions. \( 2 \sqrt{k}+\sqrt{k}-3 \sqrt{k} \) \( \sqrt{3 k} \) \( 0-\sqrt{k} \) 0
