Question

Simplifique os radicais e efetue as operações:

Answer 1

Explicação passo-a-passo:

a) $\sqrt{2}-\sqrt{8}= \sqrt{2}-2\sqrt{2}=-\sqrt{2}$

b) $\sqrt{54}+\sqrt{96}=3\sqrt{6}+4\sqrt{6}=7\sqrt{6}$

c) $\sqrt{63}-\sqrt{28}=3\sqrt{7}-2\sqrt{7}=\sqrt{7}$

d) $-\sqrt{12}+6\sqrt{3}=-2\sqrt{3}+6\sqrt{3}=4\sqrt{3}$

e) $\sqrt[5]{64} -3\sqrt[5]{2} =2\sqrt[5]{2} -3\sqrt[5]{2} =- \sqrt[5]{2}$

f) $2\sqrt{27} -\sqrt{75} =2(3\sqrt{3} )-5\sqrt{3} =6\sqrt{3} -5\sqrt{3}=\sqrt{3}$
