Question

Divida os radicais e simplifique o quociente
√20 : √5 =
√80:√5=
√88:√11=
√128:√4=

Answer 1

$\sqrt{20} \div \sqrt{5} = \sqrt{20\div5} = \sqrt{4} =2$

$\sqrt{80} \div \sqrt{5} = \sqrt{80\div5} = \sqrt{16} =4 \\ \\ \sqrt{88} \div \sqrt{11} = \sqrt{88\div11} = \sqrt{8} = \sqrt{2^3} =2 \sqrt{2} \\ \\ \sqrt{128} \div \sqrt{4} = \sqrt{128\div4} = \sqrt{32} = \sqrt{2^5} =4 \sqrt{2}$
