Answer 1

Resposta:

Explicação passo-a-passo:

a)

$2\sqrt{3}+5\sqrt{3}+4\sqrt{3}\\= 11\sqrt{3}$

b)

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

c)

$3\sqrt{11}-2\sqrt{11}-7\sqrt{11}\\=-6\sqrt{11}$

d)    

$7\sqrt{2}+20\sqrt{2}-14\sqrt{2}+\sqrt{2}\\=14\sqrt{2}$

e)

$\sqrt{7}+3\sqrt{7}+8\sqrt{7}-13\sqrt{7}-2\sqrt{7}\\=-3\sqrt{7}$

f)

$2\sqrt[3]{10}+6\sqrt[3]{10}-15\sqrt[3]{10}+3\sqrt[3]{10}\\=-4\sqrt[3]{10}$
