Here are the simplifications for each operation:

  1. \( \sqrt{108} \): \[ \sqrt{108} = \sqrt{36 \cdot 3} = \sqrt{36} \sqrt{3} = 6\sqrt{3} \] Response: \( 6\sqrt{3} \)

  2. \( \sqrt{15} \cdot 5 \): \[ \sqrt{15} \cdot 5 = 5\sqrt{15} \] Response: \( 5\sqrt{15} \)

  3. \( \sqrt{1223} \): Since 1223 cannot be simplified further as it does not have square factors, we keep it as is. Response: \( \sqrt{1223} \)

  4. \( \sqrt{43+27} \): \[ 43 + 27 = 70 \quad \text{and} \quad \sqrt{70} \text{ cannot be simplified further.} \] Response: \( \sqrt{70} \)

  5. \( \sqrt{312} - \sqrt{23} \): Simplifying \( \sqrt{312} = \sqrt{4 \cdot 78} = 2\sqrt{78} \): \[ 2\sqrt{78} - \sqrt{23} \text{ cannot be simplified further.} \] Response: \( 2\sqrt{78} - \sqrt{23} \)

  6. \( \sqrt{23} - \sqrt{43} \): These terms do not simplify; they remain as they are. Response: \( \sqrt{23} - \sqrt{43} \)

  7. \( \sqrt{312} \) again: This was already calculated. Response: \( 2\sqrt{78} \)

  8. \( 6\sqrt{3} \) again: This was already calculated. Response: \( 6\sqrt{3} \)

  9. \( \sqrt{75} \): \[ \sqrt{75} = \sqrt{25 \cdot 3} = 5\sqrt{3} \] Response: \( 5\sqrt{3} \)

  10. \( 2\sqrt{3} - \sqrt{312 - 23} \): First, simplify \( 312 - 23 = 289 \) so: \[ \sqrt{289} = 17 \] Therefore: \[ 2\sqrt{3} - 17 \] Response: \( 2\sqrt{3} - 17 \)

  11. \( \sqrt{73} - \sqrt{43} \): These terms cannot be simplified further; they remain as they are. Response: \( \sqrt{73} - \sqrt{43} \)

  12. \( \sqrt{43} + 27 \): This cannot have anything simplified, so it remains. Response: \( \sqrt{43} + 27 \)

  13. \( \sqrt{53} \): This is already in simplest form as well. Response: \( \sqrt{53} \)

  14. \( \sqrt{63} \): \[ \sqrt{63} = \sqrt{9 \cdot 7} = 3\sqrt{7} \] Response: \( 3\sqrt{7} \)

  15. \( \sqrt{33} \): This is already in simplest form too. Response: \( \sqrt{33} \)

  16. \( \sqrt{83} \): This one too cannot be simplified. Response: \( \sqrt{83} \)

You can plug in the responses accordingly based on this fundamental arithmetic and simplification.
