Упростите пожалуйств

Answer 1

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