Answer 1

a) $\sqrt{\frac{16}{4}} = \frac{\sqrt{16} }{\sqrt{4}} = \frac{4}{2} } = 2$

b) $\sqrt{\frac{25}{9}} = \frac{\sqrt{25} }{\sqrt{9}} = \frac{5}{3} }$

c) $\sqrt{\frac{121}{100}} = \frac{\sqrt{121} }{\sqrt{100}} = \frac{11}{10} }$

d) $\sqrt{\frac{3^{2} }{9}} = \frac{\sqrt{3^{2} } }{\sqrt{9}} = \frac{3}{3} } = 1$

e) $\sqrt{\frac{7^{2} }{49}} = \frac{\sqrt{7^{2} } }{\sqrt{49}} = \frac{7}{7} } = 1$

f) $\sqrt{\frac{36}{4}} = \frac{\sqrt{36} }{\sqrt{4}} = \frac{6}{2} } = 3$

Answer 2

Resposta:

a) $\sqrt{\frac{16}{4} } =$   $\frac{\sqrt{16} }{\sqrt{4} } = \frac{4}{2} = 2$

b) $\sqrt{\frac{25}{9} } =$  $\frac{\sqrt{25} }{\sqrt{9} } = \frac{5}{3}$

c) $\sqrt{\frac{121}{100} } =$   $\frac{\sqrt{121} }{\sqrt{100} } = \frac{11}{10}$

d) $\sqrt{\frac{3^{2} }{9} } =$   $\frac{\sqrt{3^{2} } }{\sqrt{9} } = \frac{3}{3} = 1$    

e) $\sqrt{\frac{7^{2} }{49} } =$  $\frac{\sqrt{7^{2} } }{\sqrt{49} } = \frac{7}{7} = 1$  

f) $\sqrt{\frac{36}{4} } =$   $\frac{\sqrt{36} }{\sqrt{4} } = \frac{6}{2} = 3$
