1) \( A = \sqrt{14 + 6\sqrt{5}} - \sqrt{8 - 2\sqrt{15}} \)

2) \( A = \sqrt{7 - 2\sqrt{10}} - \sqrt{7 + 2\sqrt{10}} \)

3) \( A = \sqrt{9 + 4\sqrt{2}} - \sqrt{9 - 4\sqrt{2}} \)

4) \( A = \sqrt{5 - 2\sqrt{6}} + \sqrt{3 + 2\sqrt{2}} \)

5) \( A = \sqrt{13 - 4\sqrt{3}} + \sqrt{7 - 4\sqrt{3}} \)

6) \( A = \sqrt{5 + 2\sqrt{6}} - \sqrt{5 - 2\sqrt{6}} \)

7) \( A = \sqrt{24 + 8\sqrt{5}} + \sqrt{9 - 4\sqrt{5}} \)

8) \( A = \sqrt{15 - 6\sqrt{6}} + \sqrt{33 - 12\sqrt{6}} \)

9) \( A = \sqrt{6 - 4\sqrt{2}} + \sqrt{22 - 12\sqrt{2}} \)

10) \( A = \sqrt{17 - 12\sqrt{2}} + \sqrt{9 + 4\sqrt{2}} \)
