Answer 1

Olá Paloma!!!

 

$a)\sqrt{2000}-\sqrt{500}-\sqrt{320}$

 

$\sqrt{4.5.100}-\sqrt{100.5}-\sqrt{16.4.5}$

 

$2.10\sqrt{5}-10\sqrt{5}-4.2\sqrt{5}$

 

$20\sqrt{5}-10\sqrt{5}-8\sqrt{5}$

 

$\boxed{2\sqrt{5}}$

 

 

$b)\sqrt{300}+\sqrt{50}-\sqrt{162}-\sqrt{243}$

 

$\sqrt{100.3}+\sqrt{25.2}-\sqrt{81.2}-\sqrt{81.3}$

 

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

 

$\boxed{1\sqrt{3}-4\sqrt{2}}$

 

 

$c)5\sqrt{5^4}-3\sqrt{24}-3\sqrt{250}+3\sqrt{192}$

 

$5\sqrt{5^2.5^2}-3\sqrt{4.6}-3\sqrt{25.10}+3\sqrt{64.3}$

 

$5.5.5-3.2\sqrt{6}-3.5\sqrt{10}+3.8\sqrt{3}$

 

$\boxed{125-6\sqrt{6}-15\sqrt{10}+24\sqrt{3}}$

 

 

 

$d)\sqrt{3}+\sqrt{12}$

 

$\sqrt{3}+\sqrt{4.3}$

 

$\sqrt{3}+2\sqrt{3}$

 

$\boxed{3\sqrt{3}}$

 

 

 

veja se entendeu!!!
