7)  ============

5√8 - √54 + 2√27- √162 - √108=

5*2√2- 3√6 + 2*3√3- 9√2 - 6√3=

10√2- 3√6+ 6√3- 9√2 - 6√3=√2 - 3√6

8)  ============

3/2√28 - 5/6√63 + 4√112=

3/2*2√7 - 5/6*3√7 + 4*4√7=

3√7 - 5/2√7 + 16√7 = (19 - 5/2)√7= 33/2√7

9)  ============

3∛250 - 4∛54 + 7∛16=

3∛125*2- 4∛2*27 + 7∛2*8=

3*5*∛2- 4*3∛2 + 7*2∛2=

15∛2- 12∛2 + 14∛2= 17∛2
