Answer:

hints to solve each. partial answer due to lack of time, hope it helps!

Step-by-step explanation:

a) solve ():

5 $\sqrt{3}$ + 7 $\sqrt{3}$ - 9 $\sqrt{3}$ - 6 $\sqrt{3}$ + 12 $\sqrt{3}$ - 10 $\sqrt{3}$ =

$\sqrt{3}$ . (5 +7-9-6+12-10)

b) use $\sqrt{6\\}$ = $\sqrt{3\\}\\\\$ $\sqrt{2\\}\\\\$

c) use $\sqrt{20\\}$ = $\sqrt{4\\}\\\\$ $\sqrt{5\\}\\\\$ = 2 $\sqrt{5\\}\\\\$

use $\sqrt{8\\}$ = $\sqrt{4\\}\\\\$ $\sqrt{2\\}\\\\$ = 2 $\sqrt{2\\}\\\\$

a) use $\sqrt{30\\}$ = $\sqrt{6}$ $\sqrt{5}$

use $\sqrt{30\\}$ = $\sqrt{6}$ $\sqrt{4}$ = 2 $\sqrt{6}$
