Answer 1

a.

$2 \sqrt{3} + 9 \sqrt{ 3} - 8 \sqrt{3} = 3 \sqrt{3 }$

b.

$5 \sqrt{2} - 10 \sqrt{2} + \sqrt{2} + 8 \sqrt{2} = 4 \sqrt{2}$

c.

$\sqrt{7} + \sqrt{13} + 2 \sqrt{7} - 3 \sqrt{7} + 3 \sqrt{13} - 4 \sqrt{13} = 0$

d

$4 \sqrt{2} + 30 \sqrt{2} - 7 \sqrt{2} - 5 \sqrt{2} = 22 \sqrt{7}$

e.

$14 \sqrt{3} - 10 \sqrt{7} + 24 \sqrt{3} - 30 \sqrt{3} + 12 \sqrt{3 } = 20 \sqrt{3} + 10 \sqrt{7}$

f.

$6 \sqrt{2} + 8 \sqrt{2} - 12 \sqrt{2} + 24 \sqrt{2} = 26 \sqrt{2}$

g.

$6 \sqrt{3} - 3 \sqrt{3} + 4 \sqrt{3} - 5 \sqrt{3} + 10 \sqrt{3 } = 12 \sqrt{3}$

h

$10 \sqrt{5} + 5 \sqrt{5} - 8 \sqrt{5} + 3 \sqrt{2} - 9 \sqrt{5} = 3 \sqrt{2} - 2 \sqrt{3}$

i.

$6 \sqrt{2} - 9 \sqrt{2} +11 \sqrt{2} - 10 \sqrt{2} + 7 \sqrt{2} = 5 \sqrt{2}$
