Answer 1

$displaystyle tt 1) : 4sqrt{3}-sqrt{48}=4sqrt{3}-4sqrt{3}=0\displaystyle tt 2) : sqrt{24}-2sqrt{600}=2sqrt{6}-20sqrt{6}=-18sqrt{6}\displaystyle tt 3) : sqrt{20}-sqrt{125}+sqrt{405}=2sqrt{5}-5sqrt{5}+sqrt{405}=6sqrt{5}\displaystyle tt 4) : frac{1}{3}sqrt{45}+sqrt{80}=sqrt{5}+4sqrt{5}=5sqrt{5}\displaystyle tt 5) : 5sqrt{7}-sqrt{700}-0,5cdot sqrt{125}=5sqrt{7}-10sqrt{7}-0,5cdot 5sqrt{5}=-5sqrt{7}-2,5sqrt{5}$
