Answer 1

Răspuns:

Explicație pas cu pas:

$5 = \sqrt{25} < \sqrt{28} < \sqrt{36}= 6$

$5 = \sqrt{25} < \sqrt{32} < \sqrt{36}= 6$

$3 = \sqrt{9} = \sqrt{\frac{45}{5}} < \sqrt{\frac{74}{5} } < \sqrt{\frac{80}{5} } = \sqrt{16}= 4$

$6 = \sqrt{36} = \sqrt{\frac{72}{2}} < \sqrt{\frac{81}{2} } < \sqrt{\frac{98}{2} } = \sqrt{49}= 7$

$20 = \sqrt{400} < \sqrt{405,23 } < \sqrt{441 } = 21$

$0 = \sqrt{0} = \sqrt{\frac{0}{325}}<\sqrt{\frac{1}{325}} < \sqrt{\frac{325}{325} }= \sqrt{1} = 1$

$4 = \sqrt{16} = \sqrt{\frac{64}{4}} < \sqrt{\frac{85}{4} } < \sqrt{\frac{100}{4} } = \sqrt{25}= 5$

$0 = \sqrt{0} = \sqrt{\frac{0}{100}} < \sqrt{\frac{1,234}{100} } < \sqrt{\frac{100}{100} } = \sqrt{1}=1$
