Question

efetue as multiplicações e as divisões indicando os radicais √50:√2= √2.√8= √3.√2.√6= √80:√5= √2.√10.√5=
3. 3
√54:√2=

Answer 1

$\sqrt{50} \div \sqrt{2} = \sqrt{50\div2} = \sqrt{25} =5 \\ \\ \sqrt{2} \times \sqrt{8} = \sqrt{2\times8} = \sqrt{16} =4 \\ \\ \sqrt{3} \times \sqrt{2} \times \sqrt{6} = \sqrt{3\times2\times6} = \sqrt{36} =6 \\ \\ \sqrt{80} \div \sqrt{5} = \sqrt{80\div5} = \sqrt{16} =4 \\ \\ \sqrt{2} \times \sqrt{10} \times \sqrt{5} = \sqrt{2\times10\times5} = \sqrt{100} =10 \\ \\ \sqrt[3]{54} \div \sqrt[3]{2} = \sqrt[3]{54\div2} = \sqrt[3]{27} = \sqrt[3]{3^3} =3$
